explain_fputs_or_die(3) 				     Library Functions Manual					   explain_fputs_or_die(3)

NAME
       explain_fputs_or_die - write a string to a stream and report errors

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

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

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

       s       The s, exactly as to be passed to the fputs(3) system call.

       fp      The fp, exactly as to be passed to the fputs(3) system call.

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

       The explain_fputs_on_error function always returns the value return by the wrapped fputs(3) system call.

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

SEE ALSO
       fputs(3)
	       write a string to a stream

       explain_fputs(3)
	       explain fputs(3) errors
