Function Definition

 void glClampColor(GLenum target, GLenum clamp);
target

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.
