# Gl.DeleteProgram (gb.opengl.glsl)

Static Sub DeleteProgram ( Program As Integer )

Deletes a program object.

### Parameters

program

  Specifies the program object to be deleted.

### Description

Gl.DeleteProgram 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 Gl.CreateProgram.

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 Gl.DeleteShader. A value of 0 for program will be silently ignored.

To determine whether a program object has been flagged for deletion, call Gl.GetProgram with arguments program and Gl.DELETE_STATUS.

### Errors

Gl.INVALID_VALUE is generated if program is not a value generated by OpenGL.

### Associated Gets

Gl.Get with argument Gl.CURRENT_PROGRAM

Gl.GetProgram with arguments program and Gl.DELETE_STATUS

Gl.IsProgram
