XThis file is in X.IR profile (5) Xformat and consists of a stanza containing bindings. XThese bindings consist of key/value pairs. XThere may be multiple values for each key. X.PP XThe stanza contained in the X.I .alphabetize Xfile should contain one stanza with the marker X.I alphabetize. XThis stanza may contain three keys: X.I skipchars, X.I mapctrlsequence Xand X.I mapindexentry. X.PP X.I Skipchars Xis a list of characters to ignore when alphabetizing index entries. X.PP X.I Mapctrlsequence Xis a list of pairs of values. XThe odd numbered value X.I n X(a control sequence) Xmaps into the even value X.I n+1 X(any text). XThe leading backslash may Xbe omitted for the odd control sequence strings. X.PP X.I Mapindexentry Xis a list of index entries to match exactly. XThe odd numbered value X.I n X(an index entry) maps into the even value X.I n+1 X(any text). XThe backslashes Xmay not be omitted here. X.SH EXAMPLES XHere is an example stanza to help clarify some ideas.

X.IR Profile (5) Xrequires escaping the ^, ' and \e. X.PP XThe control word X.I \etrwlogo Xwill be treated as the string X.I TRW Xwherever it occurs in an index entry Xand the control word X.I \eLaTeX Xwill be treated as X.I LaTeX Xwherever it occurs in an index entry. XNote that the leading backslash in the third value (i.e., X.IR \eLaTeX ) Xcan be omitted without ill effect. XNormally, control words and control symbols are removed when alphabetizing.

X.SH COMMENTS XThe X.I mapindexentry Xentries are examined first and must completely match an index entry. XIf they match, no other alphabetizing substitution takes place. X.br XUpper and lower case letters are equivalent when sorting. XUpper case alphabetics are converted to lower case; consequently, Xmost non-alphabetic characters precede the alphabetic characters Xin the ASCII collating sequence. XThe exception are the characters {, |, } and ~. X.br XBlanks are ignored when sorting. X.br XAfter control sequences are expanded into their logical sort string, Xthey are not scanned for X.I skipchars. X.br XLowercase roman numerals are recognized when the \epagestyle is roman.

X.I Profile_marker_space Xallocates storage for a marker including sufficient space for X.I n Xcharacters of text plus a terminating null byte. X.I Profile_binding_space Xallocates storage for a binding including sufficient space for X.I n Xcharacters of name text plus a terminating null byte. X.I Profile_value_space Xallocates storage for a value. XIf X.I n Xis positive and non-zero the component X.IR value . s Xis initialized as a X.IR n +1 Xcharacter array. XAll of the above routines return a pointer on success and X.B NULL Xon failure. XAll storage is zero filled. XThe routine X.IR free (3) Xmay be safely used to release storage allocated by these routines.

X.PP XEach profile is an ASCII file containing a sequence of one or more X.IR stanzas . XEach stanza in turn consists of a sequence of X.I markers Xfollowed by a sequence of X.IR bindings . XThe characters `{' (left brace) and `}' (right brace) Xdelimit the beginning and end respectively of the stanza bindings. XEach binding consists of a name Xfollowed by an optional sequence of values. X.SH MARKERS XMarkers are arbitrary patterns in the style of X.IR glob (3) Xdelimited by white space. XThe list of markers may be empty. XThere is no limit to the number of markers. XExamples of markers are: X.nf X X queue X /usr/lib X 1776 X a_long_marker X file[0-9]*.? X.fi X.SH BINDINGS XBindings are the association of names with values. XThere is one binding to a line each consisting of a name followed Xby an optional sequence of values. XNames and values are separated, Xone from the other, Xby blanks or tabs. XHere a newline preceded by a backslash is equivalent to a blank. XThe list of bindings may be empty. XThere is no limit to the number of bindings. XBy convention each binding is indented by a single tab. X.SH NAMES XNames are arbitrary patterns in the style of X.IR glob (3) Xdelimited by white space. X.SH VALUES XValues are Xinteger, Xreal, Xoctal, Xhex, Xcharacter, Xor Xstring Xconstants. XArbitrary text, Xnot recognizably one of the aforementioned types, Xis classified as X.I other Xand is a legitimate value. X.TP Xinteger XA sequence of digits optionally preceded by a minus sign. XEvery integer constant is taken to be long. X.TP Xfloating XA floating constant consists of an optional minus sign, Xan integer part Xa decimal point, Xa fraction part, Xan X.B e Xor X.BR E , Xand an optionally signed integer exponent. XThe integer and fraction parts both consist of a sequence of digits. XEither the integer part or the fraction part (not both) Xmay be missing; Xeither the decimal point or the X.B e Xand the exponent (not both) may be missing. XEvery floating constant is taken to be double-precision. X.TP Xhex XA sequence of hexidecimal digits preceded by X.B 0x Xor X.BR 0X . XThe hexidecimal digits are 0-9, a-e and A-F. XEvery hex constant is taken to be long. X.TP Xoctal XA sequence of octal digits preceded by X.B 0o Xor X.B 0O X(digit zero followed by a letter o). XThe octal digits are 0-7. XEvery octal constant is taken to be long. X.TP Xcharacter XA character constant is a character enclosed in single quotes. XCertain non-graphic characters, Xthe single quote ', Xthe caret ^ and Xthe backslash \\, Xmay be represented according to the following table of escape sequences: X.ta 1i +\w'carriage return 'u X.nf X X newline \\n X horizontal tab \\t X backspace \\b X carriage return \\r X form feed \\f X escape \\e X backslash \\\\ X single quote \\' X caret \\^ X control-@ ^@ X control-A ^A X ... ... X control-Z ^Z X control-[ ^[ X control-\\ ^\\ X control-^ ^^ X control-_ ^_ X delete ^? X bit pattern \\\fIddd\fR X X.fi X.DT XThe escape \\\fIddd\fR Xconsists of the backslash followed by 1, 2, or 3 octal digits Xwhich are taken to specify the value of the desired character. XIf the character following a backslash (caret) is not one of those Xspecified, the backslash (caret) is ignored. X.TP Xstring XA string is a sequence of characters surrounded by double quotes, as in X\fB"..."\fR. XIn a string, Xthe double quote character \fB"\fR must be preceded by a \\; Xin addition, Xthe same escapes as described for character constants may be used. X.PP XExamples of values are: X.nf X X 7 X -1.293e3 X 0x10a5 X 0o1273 X 'x' X "a string" X an_other_value X.fi X.SH COMMENTS XComments may appear anywhere within a profile. XThey are introduced by the character `#' and are terminated by Xthe succeeding newline. X.SH EXAMPLES XThe empty stanza.

XBasically, the include file is divided up into four sections: Xmachine Xenvironment Xinformation, Xstandard type definitions, Xuseful constants and useful macros. X.PP XThe environment of the computer a program is executing on is described by Xthe following defines: X.TP XHAS_UNSIGNED_SHORT XIf defined, unsigned shorts are supported. X.TP XCHAR_IS_SIGNED XIf defined, chars are signed. X.TP XHAS_UNSIGNED_CHAR XIf defined, unsigned chars are supported. X.TP XHAS_UNSIGNED_LONG XIf defined, unsigned longs are supported. X.TP XHAS_VOID XIf defined, the void function type is supported. X.TP XBITS_PER_CHAR XDefined as the number of bits in a char. X.TP XBITS_PER_SHORT XDefined as the number of bits in a short. X.TP XBITS_PER_INT XDefined as the number of bits in an int. X.TP XBITS_PER_LONG XDefined as the number of bits in a long. X.TP XBITS_PER_POINTER XDefined as the number of bits in a pointer. X.PP XThere are a set of machine independent type definitions and macros. X.TP XTiny XA signed character type. X.TP XTINY(\fIx\fP) XAn extraction macro for a signed character. The value of the macro is an Xinteger that will be sign extended if the most significant bit of the Xcharacter is one. X.TP XUnsignedTiny XAn unsigned character type. X.TP XUNSIGNED_TINY(\fIx\fP) XAn extraction macro for an unsigned character. The value of the macro is an Xinteger that will not be signed extended even if the most significant bit Xof the character is one. X.TP XShort XSimply a short type. All compilers have a short type but this is included Xfor lexical consistency. X.TP XUnsignedShort XAn unsigned short type. X.TP XUNSIGNED_SHORT(\fIx\fP) XAn extraction macro for an unsigned short. XThe value of the macro is an integer that will not be sign extended even if Xthe most significant bit of the short is one. X.TP XInteger XThe int type. Included for lexical consistency. X.TP XUnsignedInteger XThe unsigned integer type. X.TP XLong XThe long type. X.TP XUnsignedLong XAn unsigned long type. X.TP XUNSIGNED_LONG(\fIx\fP) XAn extraction macro for an unsigned long integer.

X.TP XImport XThe storage class used when importing variables from separate files. XIt is defined to be the keyword X.I extern. X.TP XExport XThe storage class used when exporting variables from separate files. XIn C, you needn't Xdeclare that a variable is available to other files if it is declared Xoutside a function so this is defined as a no-op. X.TP XLocal XThe static storage class. X.PP XA number of useful constants are also defined. X.TP XTRUE and FALSE XThe values 1 and 0 respectively. X.TP XSUCCEED and FAIL XThe values 0 and 1 respectively. These are normally used as exit statuses. X.TP XON XA long with all the bits set. X.TP XOFF XA long with no bits set. X.TP XSTANDARD_IN XDefined as 0. X.TP XSTANDARD_OUT XDefined as 1.

X.PP XA number of useful macro are also defined. X.TP XMAX(\fIx\fP, \fIy\fP) XReturns the maximum value of X.I x Xand X.I y. X.TP XMIN(\fIx\fP, \fIy\fP) XReturns the minimum value of X.I x Xand X.I y. X.TP XABS(\fIx\fP) XReturns the absolute value of its parameter. This works for integers and Xreals. X.TP XROUND(\fIx\fP) XReturns Xits parameter rounded to the nearest integer value. X.TP XCEILING(\fIx\fP) XReturns the ceiling of its parameter. X.TP XFLOOR(\fIx\fP) XReturns the floor of its parameter. X.TP XEQ(\fIs\fP, \fIt\fP) XReturns true if the two strings passed to it as parameters are equal.
