Description

pinterpret_item interprets an item data record obtained by a call to pread_item. 

If the item type corresponds to a function call that affects graphic representation, this function makes appropriate changes to the PHIGS state list, and generates the specified graphic output on all active workstations of categories OUTPUT and OUTIN. 

If the item type identifies user-defined data, this function generates an error indicating that it cannot interpret the item. 

Digital PHIGS Version 4.1 does not support this function.
