UTIMES(3B)UTIMES(3B)NAMEutimes - set file times
SYNOPSIS
#include <sys/time.h>
utimes(const char *file, const struct timeval tvp[2]);
DESCRIPTION
The utimes call uses the "accessed" and "updated" 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 "inode-
changed" time of the file is set to the current time.
This routine emulates the 4.3BSD utimes system call.
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. Utimes will
fail if one or more of the following are true:
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG]
A component of a pathname exceeded 255 characters, or an
entire path name exceeded 1023 characters.
[ENOENT] The named file does not exist.
[ELOOP] Too many symbolic links were encountered in translating the
pathname.
[EPERM] The process is not super-user and not the owner of the file.
[EACCES] Search permission is denied for a component of the path
prefix.
[EROFS] The file system containing the file is mounted read-only.
[EFAULT] File or tvp points outside the process's allocated address
space.
[EIO] An I/O error occurred while reading or writing the affected
inode.
NOTES
Note that prior to IRIX 6.5.10 the utimes() call only offered second
resolution because it used the utime() call internally to execute its
functionality. utimes() now uses the new utimets() call to execute its
functionality and thus now can offer the microsecond accuracy it
promises.
