Synopsis

#include "silver.h"

 

The prompt_pgroup function allows the user to select primitives to define a p-group, based on the p_type filter. The prompt specified by message is displayed at the bottom of the screen. This function uses either pick mode or scan mode to select an entity, depending on the current pick/scan setting.

 

 

Parameters

message is a null-terminated string containing a prompt message. p_type is an integer specifying the types of primitives that are to be considered for selection. p_type may be composed of any of the following flags or'ed together (as defined in silver.h):
