C SPECIFICATION
void glClampColor(GLenum target, GLenum clamp);
PARAMETERS
target
Target for color clamping. target must be GL_CLAMP_READ_COLOR.
clamp

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.
