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
