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.
