UTIME(2) — Silicon Graphics
NAME
utime − set file access and modification times
SYNOPSIS
#include <sys/types.h>
structutimbuf {
time_tactime;/∗ access time ∗/
time_tmodtime;/∗ modification time ∗/
};
int utime (path, times)
char ∗path;
struct utimbuf ∗times;
DESCRIPTION
Path points to a path name naming a file. Utime sets the access and modification times of the named file.
If times is NULL, the access and modification times of the file are set to the current time. A process must be the owner of the file or have write permission to use utime in this manner.
If times is not NULL, times is interpreted as a pointer to a utimbuf structure and the access and modification times are set to the values contained in the designated structure. Only the owner of the file or the super-user may use utime this way.
The times in the utimbuf structure are measured in seconds since 00:00:00 GMT, Jan. 1, 1970.
Utime will fail if one or more of the following are true:
The named file does not exist. [ENOENT]
A component of the path prefix is not a directory. [ENOTDIR]
Search permission is denied by a component of the path prefix. [EACCES]
The effective user ID is not super-user and not the owner of the file and times is not NULL. [EPERM]
The effective user ID is not super-user and not the owner of the file and times is NULL and write access is denied. [EACCES]
The file system containing the file is mounted read-only. [EROFS]
Times is not NULL and points outside the process’s allocated address space. [EFAULT]
Path points outside the process’s allocated address space. [EFAULT]
RETURN VALUE
Upon successful completion, a value of 0 is returned. Otherwise, a value of −1 is returned and errno is set to indicate the error.
