function file_download_access

Checks that the current user has access to a particular file.

The return value of this function hinges on the return value from file_download_headers(), which is the function responsible for collecting access information through hook_file_download().

If immediately transferring the file to the browser and the headers will need to be retrieved, the return value of file_download_headers() should be used to determine access directly, so that access checks will not be run twice.

Parameters

$uri: The URI for the file whose access should be retrieved.

Return value

Boolean TRUE if access is allowed. FALSE if access is not allowed.
