Number

OpenGL ES Extension #63

Dependencies

OpenGL ES 2.0 is required.

This extension is written against the OpenGL ES 2.0 specification.

Requires extension QCOM_extended_get to be implemented.

Overview

This extension enables instrumenting the driver for debugging of OpenGL ES 
applications.
  

New Procedures and Functions

void ExtGetShadersQCOM(uint* shaders, int maxShaders, int* numShaders);

void ExtGetProgramsQCOM(uint* programs, int maxPrograms, 
                        int* numPrograms);

boolean ExtIsProgramBinaryQCOM(uint program);

void ExtGetProgramBinarySourceQCOM(uint program, enum shadertype, 
                                   char* source, int* length)
  

Additions to OpenGL ES 2.0 Specification

The command

    void ExtGetShadersQCOM(uint* shaders, int maxShaders, int* numShaders);

returns list of shader objects in the current render context.

The command

    void ExtGetProgramsQCOM(uint* programs, int maxPrograms, int* numPrograms);

returns list of program objects in the current render context.

The command

    boolean ExtIsProgramBinaryQCOM(uint program);

returns boolean indicating if the program is created with ProgramBinaryOES.

The command

    void ExtGetProgramBinarySourceQCOM(uint program, enum shadertype, char* source, int* length)

returns source string, if any exists, for program created with ProgramBinaryOES.

Errors

INVALID_VALUE error will be generated if the <program> parameter to
ExtIsProgramBinaryQCOM does not reference to a valid program object.

INVALID_VALUE error will be generated if the <program> parameter to
ExtGetProgramBinarySourceQCOM does not reference to a valid program object.

INVALID_ENUM error will be generated if the <shadertype> parameter to
ExtGetProgramBinarySourceQCOM is not one of the allowable values.
  

New State

None.
