NAME

       explain_setvbuf_or_die - stream buffering operations and report errors

SYNOPSIS

       #include <libexplain/setvbuf.h>
       void explain_setvbuf_or_die(FILE *fp, char *data, int mode, size_t size);
       int explain_setvbuf_on_error(FILE *fp, char *data, int mode, size_t size);

DESCRIPTION

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

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

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

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

       mode    The mode, exactly as to be passed to the setvbuf(3) system call.

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

RETURN VALUE

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

       The explain_setvbuf_on_error function always returns the value return by the wrapped setvbuf(3) system call.

EXAMPLE

       The explain_setvbuf_or_die function is intended to be used in a fashion similar to the following example:
	      explain_setvbuf_or_die(fp, data, mode, size);
