NAME
       explain_setbuffer_or_die - stream buffering operations and report errors

SYNOPSIS
       #include <libexplain/setbuffer.h>
       void explain_setbuffer_or_die(FILE *fp, char *data, size_t size);
       void explain_setbuffer_on_error(FILE *fp, char *data, size_t size);

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

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

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

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

       size    The size, exactly as to be passed to the setbuffer(3) system call.

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

       The explain_setbuffer_on_error function always returns the value return by the wrapped setbuffer(3) system call.

EXAMPLE
       The explain_setbuffer_or_die function is intended to be used in a fashion similar to the following example:
	      void result = explain_setbuffer_or_die(fp, data, size);
