The explain_strdup_or_die function is used to call the strdup(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strdup(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_strdup_on_error function is used to call the strdup(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strdup(3) function, but still returns to the caller.

data
The data, exactly as to be passed to the strdup(3) system call.

RETURN VALUE

The explain_strdup_or_die function only returns on success, see strdup(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_strdup_on_error function always returns the value return by the wrapped strdup(3) system call.

EXAMPLE

char *result = explain_strdup_or_die(data);
