glProgramBinary — load a program object with a program binary
| ||GLuint program,|
|const void *binary,|
|GLsizei length |
Specifies the name of a program object into which to load a program binary.
Specifies the format of the binary data in binary.
Specifies the address an array containing the binary to be loaded into
Specifies the number of bytes contained in
glProgramBinary loads a program object with a program binary previously returned from glGetProgramBinary.
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
GL_LINK_STATUS will be set to
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
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.
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.
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software configuration from when the program binary was produced such as having been compiled with an incompatible or outdated version of the compiler.
