SYNOPSIS¶
#include <libexplain/getc.h>
int explain_getc_or_die(FILE *fp);
DESCRIPTION¶
The
explain_getc_or_die function is used to call the

stderr,
obtained from
explain_getc(3), and then the process terminates by
calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following
example:
int c = explain_getc_or_die(fp);
- fp

system call.
- Returns:
- This function only returns on success, and returns the next
character or EOF at end of input. On failure, prints an explanation and
exits.
