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.
truncate a file to a specified length
explain ftruncate(2) errors
|
terminate the calling process |
