returns codes for allowed actions. |

The first argument is required, all others are optional. |
|
|
|
$priv is the privilege being checked. |
|
$uri contains additional information about what is being checked for access (e.g., |
|
URL, course ID etc.). |
|
$symb is the unique resource instance identifier in a course; if needed, |
|
but not provided, it will be retrieved via a call to &symbread(). |
|
$role is the role for which a priv is being checked (only used if priv is evb). |
|
$clientip is the user's IP address (only used when checking for access to portfolio |
|
files). |
|
$noblockcheck, if true, skips calls to &has_comm_blocking() for the bre priv. This |
|
prevents recursive calls to &allowed. |

Args: filename is the filename (including path) for the file for which a symb |

|
to check access status if more than one resource was found in the bighash |
|
(see rev. 1.249) to avoid an infinite loop if an ambiguous resource is part of |
|
a randompick); ignorecachednull, if true will prevent a symb of '' being |
|
returned if $env{$cache_str} is defined as ''; checkforblock if true will |
|
cause possible symbs to be checked to determine if they are subject to content |
|
blocking, if so they will not be included as possible symbs; possibles is a |
|
ref to a hash, which, as a side effect, will be populated with all possible |
|
symbs (content blocking not tested). |
