[QUOTE="OSHIMA, post: 1710106"] HI, I use the function 'fprintf' to show the 'Usage' message. if(argc != 2){ fprintf(stderr, "Usage: %s [filename]\n", argv[0]); exit(1); } perror() cannot do that. When I have to show the standard error message and more information, fprintf() is very useful for me! [/QUOTE]
