explain_truncate_or_die − truncate a file and report errors
void explain_truncate_or_die(const char *pathname, long long length);
The explain_truncate_or_die function is used to call the truncate(2) system call. On failure an explanation will be printed to stderr, obtained from explain_truncate(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:
The pathname, exactly as to be passed to the truncate(2) system call.
The length, exactly as to be passed to the truncate(2) system call.
This function only returns on success. On failure, prints an explanation and exits.
truncate a file to a specified length
explain truncate(2) errors
terminate the calling process
