UTIMES(2)
NAME
utimes − set file times
USAGE
#include <sys/times.h>
utimes(file, tv) char *file; struct timeval tv[2];
DESCRIPTION
The utimes call uses the “accessed” and “updated” times in that order from the tv vector to set the corresponding recorded times for file.
The caller must be the owner of the file or the super-user. The “inode-changed” time of the file is set to the current time.
RETURN VALUE
A successful call returns zero. A failed call returns -1 and sets errno as indicated below.
