NAME
utime -- set file times LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <utime.h> int utime(const char *path, const struct utimbuf *times); DESCRIPTION
This interface is obsoleted by utimes(2). The utime() function sets the access and modification times of the named file, based on the actime and modtime fields of the struct utimbuf pointed at by times. If the times are specified (the times argument is non-NULL), the caller must be the owner of the file or be the super-user. If the times are not specified (the times argument is NULL), the caller must be the owner of the file, have permission to write the file, or be the super-user. ERRORS
The utime() function may fail and set errno for any of the errors specified for the library function utimes(2). SEE ALSO
stat(2), utimes(2) STANDARDS
The utime() function conforms to IEEE Std 1003.1-1988 (``POSIX.1''). HISTORY
A utime() function appeared in Version 7 AT&T UNIX. BSD
June 4, 1993 BSD

NAME
utime, utimes - change access and/or modification times of an inode SYNOPSIS
#include <sys/types.h> #include <utime.h> int utime(const char *filename, struct utimbuf *buf); #include <sys/time.h> int utimes(char *filename, struct timeval *tvp); DESCRIPTION
utime changes the access and modification times of the inode specified by filename to the actime and modtime fields of buf respectively. If buf is NULL, then the access and modification times of the file are set to the current time. The utimbuf structure is: struct utimbuf { time_t actime; /* access time */ time_t modtime; /* modification time */ }; In the Linux DLL 4.4.1 libraries, utimes is just a wrapper for utime: tvp[0].tv_sec is actime, and tvp[1].tv_sec is modtime. The timeval structure is: struct timeval { long tv_sec; /* seconds */ long tv_usec; /* microseconds */ }; RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately. ERRORS
Other errors may occur. EACCES Permission to write the file is denied. ENOENT filename does not exist. CONFORMING TO
utime: SVr4, SVID, POSIX. SVr4 documents additional error conditions EFAULT, EINTR, ELOOP, EMULTIHOP, ENAMETOOLONG, ENOLINK, ENOTDIR, ENO- LINK, ENOTDIR, EPERM, EROFS. utimes: BSD 4.3 SEE ALSO
