Description

When the application calls popen_phigs, 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. 

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