SYNOPSIS

9       #include <libexplain/fputs.h>
10       void explain_fputs_or_die(const char *s, FILE *fp);
11       int explain_fputs_on_error(const char *s, FILE *fp);

DESCRIPTION

14       The  explain_fputs_or_die  function is used to call the fputs(3) system
15       call. On failure an explanation will be  printed  to  stderr,  obtained
16       from  the explain_fputs(3) function, and then the process terminates by
17       calling exit(EXIT_FAILURE).
18
19       The explain_fputs_on_error function is used to call the fputs(3) system
20       call.  On  failure  an  explanation will be printed to stderr, obtained
21       from the explain_fputs(3) function, but still returns to the caller.
22
23       s       The s, exactly as to be passed to the fputs(3) system call.
24
25       fp      The fp, exactly as to be passed to the fputs(3) system call.
26

RETURN VALUE

28       The explain_fputs_or_die function only returns on success, see fputs(3)
29       for  more  information. On failure, prints an explanation and exits, it
30       does not return.
31
32       The explain_fputs_on_error function always returns the value return  by
33       the wrapped fputs(3) system call.
34

EXAMPLE

36       The  explain_fputs_or_die  function is intended to be used in a fashion
37       similar to the following example:
38              explain_fputs_or_die(s, fp);
