glIsTexture - determine if a name corresponds to a texture

GLboolean glIsTexture(GLuint 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.
