glDeleteProgram — Deletes a program object
void glDeleteProgram( | GLuint | program); |
glDeleteProgram frees the memory and
invalidates the name associated with the program object
specified by program. This command
effectively undoes the effects of a call to
glCreateProgram.
If a program object is in use as part of current rendering
state, it will be flagged for deletion, but it will not be
deleted until it is no longer part of current state for any
rendering context. If a program object to be deleted has shader
objects attached to it, those shader objects will be
automatically detached but not deleted unless they have already
been flagged for deletion by a previous call to
glDeleteShader.
A value of 0 for program will be silently
ignored.
To determine whether a program object has been flagged for
deletion, call
glGetProgram
with arguments program and
GL_DELETE_STATUS.
GL_INVALID_VALUE is generated if
program is not a value generated by
OpenGL.
GL_INVALID_OPERATION is generated if
glDeleteProgram is executed between the
execution of
glBegin
and the corresponding execution of
glEnd.
