explain_fputc_or_die - output of characters and report errors
#include <libexplain/fputc.h>
void explain_fputc_or_die(int c, FILE *fp);
The
explain_fputc_or_die function is used to call the
fputc(3)
system call. On failure an explanation will be printed to
stderr,
obtained from
explain_fputc(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:
explain_fputc_or_die(c, fp);
- c
- The c, exactly as to be passed to the fputc(3) system call.
- fp
- The fp, exactly as to be passed to the fputc(3) system call.
- Returns:
- This function only returns on success. On failure, prints an explanation
and exits.
- fputc(3)
- output of characters
- explain_fputc(3)
- explain fputc(3) errors
- exit(2)
- terminate the calling process
