NAME

       explain_setbuf_or_die - set stream buffer and report errors

SYNOPSIS

       #include <libexplain/setbuf.h>
       void explain_setbuf_or_die(FILE *fp, char *data);
       void explain_setbuf_on_error(FILE *fp, char *data);

DESCRIPTION

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

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

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

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

RETURN VALUE

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

       The  explain_setbuf_on_error  function  always  returns  the value return by the wrapped setbuf(3) system
       call.

EXAMPLE

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