GLUNIFORMSUBROUTINES(3G)        [FIXME: manual]       GLUNIFORMSUBROUTINES(3G)

NAME
       glUniformSubroutines - load active subroutine uniforms

C SPECIFICATION
       void glUniformSubroutinesuiv(GLenum shadertype, GLsizei count,
                                    const GLuint *indices);

PARAMETERS
       shadertype
           Specifies the shader stage from which to query for subroutine
           uniform index.  shadertype must be one of GL_VERTEX_SHADER,
           GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER,
           GL_GEOMETRY_SHADER or GL_FRAGMENT_SHADER.

       count
           Specifies the number of uniform indices stored in indices.

       indices
           Specifies the address of an array holding the indices to load into
           the shader subroutine variables.

DESCRIPTION
       glUniformSubroutines loads all active subroutine uniforms for shader
       stage shadertype of the current program with subroutine indices from
       indices, storing indices[i] into the uniform at location i.  count must
       be equal to the value of GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the
       program currently in use at shader stage shadertype. Furthermore, all
       values in indices must be less than the value of GL_ACTIVE_SUBROUTINES
       for the shader stage.

ERRORS
       GL_INVALID_OPERATION is generated if no program object is current.

       GL_INVALID_VALUE is generated if count is not equal to the value of
       GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader stage shadertype
       of the current program.

       GL_INVALID_VALUE is generated if any value in indices is geater than or
       equal to the value of GL_ACTIVE_SUBROUTINES for the shader stage
       shadertype of the current program.

       GL_INVALID_ENUM is generated if shadertype is not one of the accepted
       values.
