Name

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

C Specification

void glDetachShader(GLuint  program,
 GLuint  shader);

Parameters

program

Specifies the program object from which to detach the shader object.

shader

Description

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.

glDetachShader is available only if the GL version is 2.0 or greater.

Errors

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.

GL_INVALID_OPERATION is generated if glDetachShader is executed between the execution of glBegin and the corresponding execution of glEnd.
