|
||
|
|
|

|
|
||
|
|
## 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](_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](_GL_FALSE).
|
||
|
|
|
||
|
|
A name returned by [_glGenTextures](_glGenTextures), but not yet associated with a texture by calling [_glBindTexture](_glBindTexture), is not the name of a texture.
