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       such as having been compiled with an incompatible or outdated version of the compiler.
