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);
