glDeleteShader — Deletes a shader object
void glDeleteShader( | GLuint | shader); |
glDeleteShader frees the memory and
invalidates the name associated with the shader object specified
by shader. This command effectively
undoes the effects of a call to
glCreateShader.
If a shader object to be deleted is attached to a program
object, it will be flagged for deletion, but it will not be
deleted until it is no longer attached to any program object,
for any rendering context (i.e., it must be detached from
wherever it was attached before it will be deleted). A value of
0 for shader will be silently
ignored.
To determine whether an object has been flagged for
deletion, call
glGetShader
with arguments shader and
GL_DELETE_STATUS.
GL_INVALID_VALUE is generated if
shader is not a value generated by
OpenGL.
GL_INVALID_OPERATION is generated if
glDeleteShader is executed between the
execution of
glBegin
and the corresponding execution of
glEnd.
