GLGETUNIFORMSUBROUTI(3G) [FIXME: manual] GLGETUNIFORMSUBROUTI(3G) NAME
glGetUniformSubroutine - retrieve the value of a subroutine uniform of a given shader stage of the current program C SPECIFICATION
void glGetUniformSubroutineuiv(GLenum shadertype, GLint location, GLuint *values); 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. location Specifies the location of the subroutine uniform. values Specifies the address of a variable to receive the value or values of the subroutine uniform. DESCRIPTION
glGetUniformSubroutine retrieves the value of the subroutine uniform at location location for shader stage shadertype of the current program. location must be less than the value of GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader currently in use at shader stage shadertype. The value of the subroutine uniform is returned in values. ERRORS
GL_INVALID_ENUM is generated if shadertype is not one of the accepted values. GL_INVALID_VALUE is generated if location is greater than or equal to the value of GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader currently in use at shader stage shadertype. GL_INVALID_OPERATION is generated if no program is active. SEE ALSO

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. ASSOCIATED GETS
