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.

ASSOCIATED GETS
