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

       exit(2) terminate the calling process

explain_strtoull_or_die(3)				     Library Functions Manual					explain_strtoull_or_die(3)

NAME

       explain_strtoull_or_die - convert string to integer and report errors

SYNOPSIS

       #include <libexplain/strtoull.h>
       unsigned long long explain_strtoull_or_die(const char *nptr, char **endptr, int base);
       unsigned long long explain_strtoull_on_error(const char *nptr, char **endptr, int base))

DESCRIPTION

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

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

       nptr    The nptr, exactly as to be passed to the strtoull(3) system call.

       endptr  The endptr, exactly as to be passed to the strtoull(3) system call.

       base    The base, exactly as to be passed to the strtoull(3) system call.

RETURN VALUE

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

       The explain_strtoull_on_error function always returns the value return by the wrapped strtoull(3) system call.

EXAMPLE

       The explain_strtoull_or_die function is intended to be used in a fashion similar to the following example:
	      unsigned long long result = explain_strtoull_or_die(nptr, endptr, base);

SEE ALSO

       strtoull(3)
	       convert a string to an unsigned long integer

       explain_strtoull(3)
	       explain strtoull(3) errors

       exit(2) terminate the calling process
