NAME

mt_fok, mt_ferr - shortcut macro to test if function executed as expected.

SYNOPSIS

#include <mtest.h>

mt_fok(function_call)
mt_ferr(function_call, errno_value)

DESCRIPTION

Macros are a simple shortcuts to perform test on functions that return either -1 or 0. By convention 0 means success and -1 means error and error reason is stored in errno variable. If function returns different values than 0 or -1, ordinary mt_fail(3) should be used instead.

mt_fok(3) simply expects that function returns 0.

mt_ferr(3) expects function to return -1, and sets errno value to errno_value.

Both functions uses mt_fail(3) under the hood.

EXAMPLE

#include <mtest.h>
#include <errno.h>

mt_defs();

    static int f1(void)
    {
        return 0;
    }

    static int f2(void)
    {
        errno = ENOSYS;
        return -1;
    }

    static void t1(void)
    {
        mt_fok(f1());
        mt_ferr(f2(), ENOSYS);
    }

    int main(void)
    {
        mt_run(t1);
        mt_return();
    }
