shadertype
count
indices
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.
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.
