""- TASK INTERRUPTION - Detection of Ctrl-C and Ctrl-D is provided in the I/O library. If the external integer location Enable_Abort is set to non-zero a check for these conditions is performed every time a level-1 I/O call is made. If either of these keys were pressed, the appropriate character is echoed to stdout, all level-1 files are closed, and the program terminates. Programs that do not use level-1 I/O or that wish to check more frequently may call the function Chk_Abort(), which will return zero if neither of the keys were pressed, or the signal value if either key was pressed. Note that if Enable_Abort is non- zero a successful call to Chk_Abort (either key had been pressed) will result in program termination as described above."" CAUTION: The closing of files and freeing of memory that is done "for you" by C is limited to the files and memory allocation that the C runtime system knows about (documented in the C manual). If you use any ROM or AmigaDOS routines (documented else where) C will NOT clean those up. (Good /Amiga/ programmers clean up after themselves)
