NAME

       glShaderBinary - load pre-compiled shader binaries

C SPECIFICATION

       void glShaderBinary(GLsizei count, const GLuint *shaders, GLenum binaryFormat, const void *binary, GLsizei length);

PARAMETERS

       count
	   Specifies the number of shader object handles contained in shaders.

       shaders
	   Specifies the address of an array of shader handles into which to load pre-compiled shader binaries.

       binaryFormat
	   Specifies the format of the shader binaries contained in binary.

       binary
	   Specifies the address of an array of bytes containing pre-compiled binary shader code.

       length
	   Specifies the length of the array whose address is given in binary.

DESCRIPTION

       glShaderBinary loads pre-compiled shader binary code into the count shader objects whose handles are given in shaders.  binary points to
       length bytes of binary shader code stored in client memory.  binaryFormat specifies the format of the pre-compiled code.

       The binary image contained in binary will be decoded according to the extension specification defining the specified binaryFormat token.
       OpenGL does not define any specific binary formats, but it does provide a mechanism to obtain token vaues for such formats provided by such
       extensions.

       Depending on the types of the shader objects in shaders, glShaderBinary will individually load binary vertex or fragment shaders, or load
       an executable binary that contains an optimized pair of vertex and fragment shaders stored in the same binary.

ERRORS

       GL_INVALID_OPERATION is generated if more than one of the handles in shaders refers to the same shader object.

       GL_INVALID_ENUM is generated if binaryFormat is not an accepted value.

       GL_INVALID_VALUE is generated if the data pointed to by binary does not match the format specified by binaryFormat.

ASSOCIATED GETS

       glGet() with parameter GL_NUM_SHADER_BINARY_FORMATS.

       glGet() with parameter GL_SHADER_BINARY_FORMATS.

NAME

       glGetAttachedShaders - Returns the handles of the shader objects attached to a program object

C SPECIFICATION

       void glGetAttachedShaders(GLuint program, GLsizei maxCount, GLsizei *count, GLuint *shaders);

PARAMETERS

       program
	   Specifies the program object to be queried.

       maxCount
	   Specifies the size of the array for storing the returned object names.

       count
	   Returns the number of names actually returned in objects.

       shaders
	   Specifies an array that is used to return the names of attached shader objects.

DESCRIPTION

       glGetAttachedShaders returns the names of the shader objects attached to program. The names of shader objects that are attached to program
       will be returned in shaders.  The actual number of shader names written into shaders is returned in count.  If no shader objects are
       attached to program, count is set to 0. The maximum number of shader names that may be returned in shaders is specified by maxCount.

       If the number of names actually returned is not required (for instance, if it has just been obtained by calling glGetProgram()), a value of
       NULL may be passed for count. If no shader objects are attached to program, a value of 0 will be returned in count. The actual number of
       attached shaders can be obtained by calling glGetProgram() with the value GL_ATTACHED_SHADERS.

ERRORS

       GL_INVALID_VALUE is generated if program is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if program is not a program object.

       GL_INVALID_VALUE is generated if maxCount is less than 0.

ASSOCIATED GETS

       glGetProgram() with argument GL_ATTACHED_SHADERS
