glIsTexture — determine if a name corresponds to a texture

C Specification

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.


glIsTexture is available only if the GL version is 1.1 or greater.


GL_INVALID_OPERATION is generated if glIsTexture is executed between the execution of glBegin and the corresponding execution of glEnd.
