explain_getc_or_die − input of characters and report errors
#include <libexplain/getc.h>
int explain_getc_or_die(FILE *fp);
The explain_getc_or_die function is used to call the getc(3) system call. On failure an explanation will be printed to 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 |
The fp, exactly as to be passed to the getc(3) 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.
