GLPROGRAMPARAMETER(3G) [FIXME: manual] GLPROGRAMPARAMETER(3G) NAME
glProgramParameter - specify a parameter for a program object C SPECIFICATION
void glProgramParameteri(GLuint program, GLenum pname, GLint value); PARAMETERS
program Specifies the name of a program object whose parameter to modify. pname Specifies the name of the parameter to modify. value Specifies the new value of the parameter specified by pname for program. DESCRIPTION
glProgramParameter specifies a new value for the parameter nameed by pname for the program object program. If pname is GL_PROGRAM_BINARY_RETRIEVABLE_HINT, value should be GL_FALSE or GL_TRUE to indicate to the implementation the intention of the application to retrieve the program's binary representation with glGetProgramBinary(). The implementation may use this information to store information that may be useful for a future query of the program's binary. It is recommended to set GL_PROGRAM_BINARY_RETRIEVABLE_HINT for the program to GL_TRUE before calling glLinkProgram(), and using the program at run-time if the binary is to be retrieved later. If pname is GL_PROGRAM_SEPARABLE, value must be GL_TRUE or GL_FALSE and indicates whether program can be bound to individual pipeline stages via glUseProgramStages(). A program's GL_PROGRAM_SEPARABLE parameter must be set to GL_TRUE before glLinkProgram() is called in order for it to be usable with a program pipeline object. The initial state of GL_PROGRAM_SEPARABLE is GL_FALSE. ERRORS
GL_INVALID_OPERATION is generated if program is not the name of an existing program object. GL_INVALID_ENUM is generated if pname is not one of the accepted values. GL_INVALID_VALUE is generated if value is not a valid value for the parameter named by pname. ASSOCIATED GETS

GLPROGRAMBINARY(3G) [FIXME: 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. ASSOCIATED GETS
