## Name

glIsBuffer — determine if a name corresponds to a buffer object

## C Specification

`GLboolean glIsBuffer(` | GLuint buffer`)`;

## Parameters

`buffer`

  Specifies a value that may be the name of a buffer object.

## Description

`glIsBuffer` returns `GL_TRUE` if `buffer` is currently the name of a buffer object. If `buffer` is zero, or is a non-zero value that is not currently the name of a buffer object, or if an error occurs, `glIsBuffer` returns `GL_FALSE`.

A name returned by glGenBuffers, but not yet associated with a buffer object by calling glBindBuffer, is not the name of a buffer object.
