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);
