NAME¶
explain_truncate_or_die - truncate a file and report errorsSYNOPSIS¶
#include <libexplain/truncate.h>void explain_truncate_or_die(const char *pathname, long long length);
DESCRIPTION¶
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:
explain_truncate_or_die(pathname, length);
- pathname
- The pathname, exactly as to be passed to the truncate(2) system call.
- length
- The length, exactly as to be passed to the truncate(2) system call.
- Returns:
- This function only returns on success. On failure, prints an explanation and exits.
