_glIsTexture: determine if a name corresponds to a texture


Syntax

 FUNCTION _glIsTexture~%% (BYVAL texture AS _UNSIGNED LONG)
 GLboolean _glIsTexture(GLuint texture);


texture
Specifies a value that may be the name of a texture.


Description

_glIsTexture returns _GL_TRUE if texture is currently the name of a texture. If texture is zero, or is a non-zero value that is not currently the name of a texture, or if an error occurs, _glIsTexture returns _GL_FALSE.

A name returned by _glGenTextures, but not yet associated with a texture by calling _glBindTexture, is not the name of a texture.
