access
======

Syntax
------

     #include <unistd.h>
     
     int access(const char *filename, int flags);

Description
-----------

This function determines what kind of access modes a given file allows.
The parameter FLAGS is the logical `or' of one or more of the following
flags:

`R_OK'
     Request if the file is readable.  Since all files are readable
     under MS-DOS, this access mode always exists.

`W_OK'
     Request if the file is writable.

`X_OK'
     Request if the file is executable.

`F_OK'
     Request if the file exists.

`D_OK'
     Request if the file is really a directory.

Return Value
------------

Zero if the requested access mode is allowed, nonzero if not.

Example
-------

     if (access("file.ext", W_OK))
       return ERROR_CANNOT_WRITE;
     open("file.ext", O_RDWR);
