NAME
    cgGLSetupSampler - initializes a sampler's state and texture object
    handle

SYNOPSIS
      #include <Cg/cgGL.h>

      void cgGLSetupSampler(CGparameter param, GLuint texobj);

PARAMETERS
    param   Specifies the sampler that will be set.

    texobj  An OpenGL texture object name. This is the value the parameter
            will be set to.

DESCRIPTION
    cgGLSetupSampler initializes a sampler; like cgGLSetTextureParameter, it
    informs the OpenGL Cg runtime which OpenGL texture object to associate
    with the sampler. Furthermore, if the sampler was defined in the source
    file with a sampler_state block that specifies sampler state, this
    sampler state is initialized for the given texture object.

    Note that in order to use the texture, either cgGLEnableTextureParameter
    must be called after cgGLSetTextureParameter and before the geometry is
    drawn, or cgGLSetManageTextureParameters must be called with a value of
    CG_TRUE.

RETURN VALUES
    cgGLSetupSampler does not return any values.

ERRORS
    CG_INVALID_PROFILE_ERROR is generated if param's profile is not a
    supported OpenGL profile.

    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter handle.

    CG_INVALID_PARAMETER_ERROR is generated param is not a texture parameter
    or if the parameter fails to set for any other reason.
