Introduction to Library Functions                        TOUCH(3)

NAME
     touch - set file access and modify times

SYNOPSIS
     #include <ast.h>

     int touch(const char* path, time_t atime, time_t mtime,  int
     force);

DESCRIPTION
     touch sets the access and modify times of the file named  by
     path.   If force != 0 then the file is created if it doesn't
     exist; otherwise the file is not created and -1 is returned.
     If force < 0 then atime and mtime are taken verbatim; other-
     wise (time_t)(-1) retains the current value for the file and
     (time_t)(0) uses the current time.

CAVEATS
     By default the change time is always changed to the  current
     time.
