wincache_fcache_meminfo - Retrieves information about file cache memory usage

SYNOPSIS

       array wincache_fcache_meminfo (void  )

DESCRIPTION

	Retrieves information about memory usage by file cache.

RETURN VALUES

	Array of meta data about file cache memory usage or FALSE on failure

	The array returned by this function contains the following elements:

	      o memory_total - amount of memory in bytes allocated for the file cache

	      o memory_free - amount of free memory in bytes available for the file cache

	      o num_used_blks - number of memory blocks used by the file cache

	      o num_free_blks - number of free memory blocks available for the file cache

	      o memory_overhead - amount of memory in bytes used for the file cache internal structures

EXAMPLES

       Example #1

	      A wincache_fcache_meminfo(3) example

	      <pre>
	      <?php
	      print_r(wincache_fcache_meminfo());
	      ?>
	      </pre>

	      The above example will output:

	      Array
	      (
		  [memory_total] => 134217728
		  [memory_free] => 131339120
		  [num_used_blks] => 361
		  [num_free_blks] => 3
		  [memory_overhead] => 5856
	      )
