NAME

       utime - set file access and modification times

SYNOPSIS

       #include <sys/types.h>
       #include <utime.h>

       int utime(const char *path, const struct utimbuf *times);

DESCRIPTION

       The  utime()  function  sets the access and modification times of the file pointed to by path,  and causes the time of the last file status
       change (st_ctime) to be updated.

       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 (defined in <utime.h>) and the access and modification times
       are set to the values contained in the designated structure. Only the owner of the file or a process that has the {PRIV_FILE_OWNER}  privi-
       lege asserted in its effective set can use utime() in this manner.

       The utimbuf structure contains the following members:

	 time_t   actime;    /* access time */
	 time_t   modtime;   /* modification time */

       The times contained in the members of the utimbuf structure are measured in seconds since 00:00:00 UTC, January 1, 1970.

RETURN VALUES

       Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The utime() function will fail if:

       EACCES	       Search permission is denied by a component of the path prefix.

       EACCES	       The process does not have appropriate privileges and is not the owner of the file, write permission is denied for the file,
		       and times is NULL.

       EFAULT	       The path argument points to an illegal address.

       EINTR	       A signal was caught during the execution of the utime() function.

       EIO	       An I/O error occurred while reading from or writing to the file system.

       ELOOP	       Too many symbolic links were encountered in translating path.

       ENAMETOOLONG    The length of the path argument exceeds PATH_MAX, or the length of a path component exceeds NAME_MAX while  _POSIX_NO_TRUNC
		       is in effect.

       ENOENT	       The named file does not exist or is a null pathname.

       ENOLINK	       The path argument points to a remote machine and the link to that machine is no longer active.

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

       EPERM	       The  effective user of the calling process is not the owner of the file, {PRIV_FILE_OWNER} is not asserted in the effective
		       set of the calling process, and times is not NULL.

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