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.
