explain_ftruncate_or_die - truncate a file and report errors
#include <libexplain/ftruncate.h> void explain_ftruncate_or_die(int fildes, long long length);
The explain_ftruncate_or_die function is used to call the ftruncate(2) system call. On failure an explanation will be printed to stderr, obtained from explain_ftruncate(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_ftruncate_or_die(fildes, length); fildes The fildes, exactly as to be passed to the ftruncate(2) system call. length The length, exactly as to be passed to the ftruncate(2) system call. Returns: This function only returns on success. On failure, prints an explanation and exits.
ftruncate(2) truncate a file to a specified length explain_ftruncate(3) explain ftruncate(2) errors exit(2) terminate the calling process
