glIsProgramPipeline determine if a name corresponds to a program pipeline object

## C Specification

GLboolean `glIsProgramPipeline` GLuint pipeline

## Parameters

pipeline

  Specifies a value that may be the name of a program pipeline object.

## Description

`glIsProgramPipeline` returns `GL_TRUE` if pipeline is currently the name of a program pipeline object. If pipeline is zero, or if `pipeline` is not the name of a program pipeline object, or if an error occurs, `glIsProgramPipeline` returns `GL_FALSE`. If pipeline is a name returned by glGenProgramPipelines, but that has not yet been bound through a call to glBindProgramPipeline, then the name is not a program pipeline object and `glIsProgramPipeline` returns `GL_FALSE`.
