glIsTexture: determine if a name corresponds to a texture
Function Definition
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.
