RocketLink!--> Man page versions: OpenBSD FreeBSD RedHat Solaris Others

[ANSI C X3.159-1989]

ASSERT(3)                 OpenBSD Programmer's Manual                ASSERT(3)

     assert - expression verification macro

     #include <assert.h>


     The assert() macro tests the given expression and if it is false, the
     calling process is terminated.  A diagnostic message is written to stderr
     and the abort(3) function is called, effectively terminating the program.

     If expression is true, the assert() macro does nothing.

     The assert() macro may be removed at compile time with the cc(1) option

     The following diagnostic message is written to stderr if expression is

           "assertion \"%s\" failed: file \"%s\", line %d\n", \
                               "expression", __FILE__, __LINE__);

     cc(1),  abort(3)

     The assert() macro conforms to ANSI X3.159-1989 (``ANSI C'').

     An assert() macro appeared in Version 6 AT&T UNIX.
