CheckGroup( )

CheckGroup( )

Checks the number of channels in a particular group

 CheckGroup(   max   [@   category   ])

Checks to see if the total number of channels in the current channel's group exceeds the max argument. If the number does not exceed max , the application continues to the next priority. If the number of channels in the group is higher than max , and priority n +101 exists (where n is the current priority), execution continues at that priority. Otherwise, the application terminates and -1 is returned.

When the optional category argument is passed, this application checks the total number of channels in the group category. See SetGroup( ) for more information about categories.
