        Parameters
| Variables | Description | 
|---|---|
| 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.
