NAME¶
glUniformSubroutines - load active subroutine uniformsC SPECIFICATION¶
void
glUniformSubroutinesuiv(GLenum shadertype,
GLsizei count,
const GLuint *indices);
PARAMETERS¶
shadertypeSpecifies 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¶
