GLPROGRAMBINARY(3G)		 OpenGL Manual		   GLPROGRAMBINARY(3G)

NAME
       glProgramBinary - load a program object with a program binary

C SPECIFICATION
       void glProgramBinary(GLuint program, GLenum binaryFormat,
			    const void *binary, GLsizei length);

PARAMETERS
       program
	   Specifies the name of a program object into which to load a program
	   binary.

       binaryFormat
	   Specifies the format of the binary data in binary.

       binary
	   Specifies the address an array containing the binary to be loaded
	   into program.

       length
	   Specifies the number of bytes contained in binary.

DESCRIPTION
       glProgramBinary loads a program object with a program binary previously
       returned from glGetProgramBinary().  binaryFormat and binary must be
       those returned by a previous call to glGetProgramBinary(), and length
       must be the length returned by glGetProgramBinary(), or by
       glGetProgram() when called with pname set to GL_PROGRAM_BINARY_LENGTH.
       If these conditions are not met, loading the program binary will fail
       and program's GL_LINK_STATUS will be set to GL_FALSE.

       A program object's program binary is replaced by calls to
       glLinkProgram() or glProgramBinary. When linking success or failure is
       concerned, glProgramBinary can be considered to perform an implicit
       linking operation.  glLinkProgram() and glProgramBinary both set the
       program object's GL_LINK_STATUS to GL_TRUE or GL_FALSE.

       A successful call to glProgramBinary will reset all uniform variables
       to their initial values. The initial value is either the value of the
       variable's initializer as specified in the original shader source, or
       zero if no initializer was present. Additionally, all vertex shader
       input and fragment shader output assignments that were in effect when
       the program was linked before saving are restored with glProgramBinary
       is called.

ERRORS
       GL_INVALID_OPERATION is generated if program is not the name of an
       existing program object.

       GL_INVALID_ENUM is generated if binaryFormat is not a value recognized
       by the implementation.

NOTES
       A program binary may fail to load if the implementation determines that
       there has been a change in hardware or software configuration from when
       the program binary was produced such as having been compiled with an
       incompatible or outdated version of the compiler.
