glDetachShader: Detaches a shader object from a program object to which it is attached

Function Definition

 void glDetachShader(GLuint program​, GLuint shader​);
Specifies the program object from which to detach the shader object.
Specifies the shader object to be detached.


glDetachShader detaches the shader object specified by shader​ from the program object specified by program​. This command can be used to undo the effect of the command glAttachShader.

If shader​ has already been flagged for deletion by a call to glDeleteShader and it is not attached to any other program object, it will be deleted after it has been detached.


GL_INVALID_VALUE is generated if either program​ or shader​ is a value that was not generated by OpenGL.

GL_INVALID_OPERATION is generated if program​ is not a program object.

GL_INVALID_OPERATION is generated if shader​ is not a shader object.

GL_INVALID_OPERATION is generated if shader​ is not attached to program​.

Associated Gets

glGetAttachedShaders with the handle of a valid program object

glGetShader with arguments shader​ and GL_DELETE_STATUS
