Syntax

POPPH (ERRFIL, BUFA)

Argument     Data Type      Access     Description
---------------------------------------------------------------------------
ERRFIL       Integer        Read       Error message file used by the
                                       application.  This is the logical
                                       unit number of the open output file.
BUFA         Integer        Read       Amount of memory units available to

                                       is required by the standard, but is

--------------------------------------------------------------------------

Description

When the application calls POPHH, Digital PHIGS performs the following actions:

•Sets the PHIGS state list to PHOP. 

•Allocates and initializes the PHIGS state list. 

•Makes the PHIGS state list, the PHIGS description table, and workstation description tables available. 

•Sets the error file entry in the error state list to the specified error log file.  A logical unit number (LUN) of 0 sends errors to SYS$ERROR (OpenVMS systems) or stderr (ULTRIX and Digital UNIX systems). 

•Optionally, allocates the specified amount of memory units.  This is implementation-dependent, and is not used by Digital PHIGS.
