NAME
utime - set file times
SYNOPSIS
#include <sys/types.h>
#include <utime.h>
int utime(const char *file, struct utimbuf *times)
DESCRIPTION
The utime call uses the "accessed" and "updated" times from
the utimbuf structure pointed to by times to set the
corresponding recorded times for file.
Struct utimbuf is defined in <utime.h> as follows:
struct utimbuf {
time_t actime; /* access time */
time_t modtime; /* modification time */
};
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 0 is returned. Oth-
erwise, a value of -1 is returned and errno is set to indi-
cate the error.
ERRORS
Utime will fail if one or more of the following are true:
[ENOTDIR] A component of the path prefix is not a
directory.
[EINVAL] The pathname contains a character with the
high-order bit set.
[ENAMETOOLONG] The path name exceeds PATH_MAX characters.
[ENOENT] The named file does not exist.
[ELOOP] Too many symbolic links were encountered in
translating the pathname. (Minix-vmd)
[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 times points outside the process's
allocated address space.
[EIO] An I/O error occurred while reading or writ-
ing the affected inode.
