Specify a parameter for a program object.

C Specification[edit]

void glProgramParameteri( GLuint program, GLenum pname, GLint value );


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 .


 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 .


 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 .
