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software configuration from when the program binary was produced such as having been compiled with an incompatible or outdated version of the compiler.
