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; otherwise (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.
