# 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`.
