NAMEexplain_fileno_or_die - check and reset stream status and report errors SYNOPSIS#include <libexplain/fileno.h> int explain_fileno_or_die(FILE *fp);
DESCRIPTIONThe explain_fileno_or_die function is used to call the fileno(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_fileno(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_fileno_on_error function is used to call the fileno(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_fileno(3) function, but still returns to the caller.
RETURN VALUEThe explain_fileno_or_die function only returns on success, see fileno(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_fileno_on_error function always returns the value return by the wrapped fileno(3) system call. EXAMPLEThe explain_fileno_or_die function is intended to be used in a fashion similar to the following example: explain_fileno_or_die(fp); SEE ALSO
