340Sstevel@tonic-gate *
350Sstevel@tonic-gate * The System V system call allows any user with write permission
360Sstevel@tonic-gate * on a file to set the accessed and modified times to the current
370Sstevel@tonic-gate * time; they specify this by passing a null pointer to "utime".
380Sstevel@tonic-gate * This is done to simulate reading one byte from a file and
390Sstevel@tonic-gate * overwriting that byte with itself, which is the technique used
400Sstevel@tonic-gate * by older versions of the "touch" command. The advantage of this
410Sstevel@tonic-gate * hack in the system call is that it works correctly even if the file
420Sstevel@tonic-gate * is zero-length.
430Sstevel@tonic-gate *
440Sstevel@tonic-gate * The BSD system call never allowed a null pointer so there should
450Sstevel@tonic-gate * be no compatibility problem there.
