glIsBuffer — determine if a name corresponds to a buffer object

C Specification

GLboolean glIsBuffer(GLuint  buffer);



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


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.


glIsBuffer is available only if the GL version is 1.5 or greater.


GL_INVALID_OPERATION is generated if glIsBuffer is executed between the execution of glBegin and the corresponding execution of glEnd.
