GLCLAMPCOLOR(3G)						   OpenGL Manual						  GLCLAMPCOLOR(3G)

NAME

       glClampColor - specify whether data read via glReadPixels() should be clamped

C SPECIFICATION

       void glClampColor(GLenum target, GLenum clamp);

PARAMETERS

       target
	   Target for color clamping.  target must be GL_CLAMP_READ_COLOR.

       clamp
	   Specifies whether to apply color clamping.  clamp must be GL_TRUE or GL_FALSE.

DESCRIPTION

       glClampColor controls color clamping that is performed during glReadPixels().  target must be GL_CLAMP_READ_COLOR. If clamp is GL_TRUE,
       read color clamping is enabled; if clamp is GL_FALSE, read color clamping is disabled. If clamp is GL_FIXED_ONLY, read color clamping is
       enabled only if the selected read buffer has fixed point components and disabled otherwise.

ERRORS

       GL_INVALID_ENUM is generated if target is not GL_CLAMP_READ_COLOR.

       GL_INVALID_ENUM is generated if clamp is not GL_TRUE or GL_FALSE.

ASSOCIATED GETS

       glGet() with argument GL_CLAMP_READ_COLOR.

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_TRUEbeforeglLinkProgram() 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

       glGetProgram().
