NAME

utimes- set file access and modification times

SYNOPSIS

#include <sys/time.h>

int utimes(const char *file, const struct timeval *times);

FEATURES

MSDOSFS, NFS_CLIENT, UFS

DESCRIPTION

utimes() sets the access and modification times of the named file from the structures in the argument array times.

The first structure is the access time. The second is the modification time.

If the times are specified, that is, if the times parameter is not NULL, then the caller must be either the owner of the file or the superuser.

If the times are not specified, that is, if the times parameter is NULL, then the caller must either be the owner of the file, have permission to write to the file or be the superuser.

PARAMETERS

utimes() supports the following parameters:

file

Name of the file for which to set access and modification times.

times

Array of structures containing the access and modification times to set.

RETURN VALUES

utimes() returns 0 on successful completion. Otherwise, utimes() returns -1 and errno is set to indicate the error.

ERRORS

utimes() will fail if:

EACCES

Search permission is denied for a component of the path prefix; or the times parameter is NULL and the effective user ID of the process does not match the owner of the file, and is not the superuser, and write access is denied.

EFAULT

file or times points outside the address space allocated to the process.

EIO

An I/O error occurred while reading or writing the affected inode.

ELOOP

Too many symbolic links were encountered in translating the pathname.

ENAMETOOLONG

A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.

ENOENT

The named file does not exist.

ENOTDIR

A component of the path prefix is not a directory.

EPERM

The times parameter is not NULL and the effective user ID does not match the owner of the file and is not the superuser.
