# glDeleteProgram

Deletes a program object

## C Specification

    		void glDeleteProgram
    		GLuint program

## Parameters

`program`

  Specifies the program object to be deleted.

## Description

`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`.

## Notes

`glDeleteProgram` is available only if the GL version is 2.0 or greater.

## Errors

`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.

## Associated Gets

glGetProgram with arguments `program` and `GL_DELETE_STATUS`
