glIsTexture function

The glIsTexture function determines if a name corresponds to a texture.

Syntax

GLboolean WINAPI glIsTexture(
   GLuint texture
);

Parameters

texture

A value that is the name of a texture.

Error codes

The following error code can be retrieved by the glGetError function.

Name	Meaning
GL_INVALID_OPERATION	The function was called between a call to glBegin and the corresponding call to glEnd.

Remarks

If the texture parameter is currently the name of a texture, the glIsTexture function returns GL_TRUE. The glIsTexture function returns GL_FALSE if texture is zero. It also returns GL_FALSE if it is a non-zero value that is not currently the name of a texture, or if an error occurs.

You cannot include calls to glIsTexture in display lists.

Note

The glIsTexture function is only available in OpenGL version 1.1 or later.
