glUniformSubroutines — load active subroutine uniforms
void glUniformSubroutinesuiv( | GLenum | shadertype, |
| GLsizei | count, | |
| const GLuint * | indices); |
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.
indicesSpecifies the address of an array holding the indices to load into the shader subroutine variables.
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.
