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.
