ERROR HANDLING (PHCL,WSCL,STCL,ARCL)

Purpose

Either the graPHIGS API supplies the Error Handling function by default, or the application supplies the function. The graPHIGS API calls the Error Handling subroutine function whenever the graPHIGS API detects an error. The default or standard Error Handling function calls the Error Logging function with the same parameters. An application supplied error handling function, which accepts the same arguments as the default error handler, may also call the Error Logging function.

See the Open PHIGS subroutine for error file specification for each supported binding. See Chapter 21. "Implementation Errors and graPHIGS API Messages for ISO PHIGS-Defined Errors" for details on implementation errors and ISO PHIGS defined errors.

Users of the FORTRAN binding may replace the default error handling subroutine with a user supplied subroutine of the same name, PERHND. C binding users may use the Set Error Handling subroutine to install a user supplied error handling function during execution time.
