AoD(3) AoD(3) NAME AoD - AssertOrDie SYNTAX #include <AF/AFUtils.h> extern void AoD(int bool, char *errmsg, ...); DESCRIPTION AoD is essentially assert(3) except that the interface is more reasonable. If the boolean is true (non zero), AoD returns. If the boolean is false (0), AoD treats the rest of its arguments as arguments to fprintf(stderr, errmsg, ...) and then calls exit(1); ARGUMENTS bool is a boolean value or an expression that evaluates to a boolean. errmsg is a format string in the style of printf(3). ... are extra optional arguments required by the format string errmsg. EXAMPLES Typical usage is: AoD(argc > 3, "%s: Usage, at least 2 arguments!\n", argv[0]); The general idea is to replace the proliferation of "fatal" subroutines that seem to crop up everywhere with a single subroutine that everyone can use.
