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
Upon successful completion, a value of zero is returned. Otherwise, a value of −1 is returned, and errno is set to indicate the error.
ERRORS
Utimes will fail if one or more of the following are true:
[EPERM] The pathname contains a character with the high-order bit set.
[ENOENT] The pathname is too long.
[ENOENT] The named file does not exist.
[ENOTDIR] A component of the path prefix is not a directory.
[EACCES] A component of the path prefix denies search permission.
[EPERM] The process is not super-user and not the owner of the file.
[EACCES] The effective user ID is not super-user and not the owner of the file; times is NULL, and write access is denied.
[EROFS] The file system containing the file is mounted read-only.
[EFAULT] Tv points outside the process’ allocated address space.
[ELOOP] The call encountered too many symbolic links in translating the pathname.
