glIsTexture — determine if a name corresponds to a texture
GLboolean glIsTexture( | GLuint texture); |
texture Specifies a value that may be the name of a texture.
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.
