C 4 utimes - set file times

#include <sys/time.h>

utimes(file, tvp)
char *file;
struct timeval *tvp[2];

The utimes call uses the \*(lqaccessed\*(rq and \*(lqupdated\*(rq times in that order from the tvp vector to set the corresponding recorded times for file.

The caller must be the owner of the file or the super-user. The \*(lqinode-changed\*(rq time of the file is set to the current time.

Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error. Utime will fail if one or more of the following are true:

15 [EPERM] The pathname contained a character with the high-order bit set.

15 [ENOENT] The pathname was too long.

15 [ENOENT] The named file does not exist.

15 [ENOTDIR] A component of the path prefix is not a directory.

15 [EACCES] A component of the path prefix denies search permission.

15 [EPERM] The process is not super-user and not the owner of the file.

15 [EACCES] The effective user ID is not super-user and not the owner of the file and times is NULL and write access is denied.

15 [EROFS] The file system containing the file is mounted read-only.

15 [EFAULT] Tvp points outside the process's allocated address space.

15 [ELOOP] Too many symbolic links were encountered in translating the pathname.
