explain_fgets_or_die - input of strings and report errors
char *explain_fgets_or_die(char *data, int data_size, FILE *fp);
The explain_fgets_or_die function is used to call the fgets(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fgets(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_fgets_or_die(data, data_size, fp);
- The data, exactly as to be passed to the fgets(3) system call.
- The data_size, exactly as to be passed to the fgets(3) system call.
- The fp, exactly as to be passed to the fgets(3) system call.
- This function only returns on success; data when a line is read, or NULL on end‐of‐file. On failure, prints an explanation and exits.
