_glIsTexture: determine if a name corresponds to a texture

  FUNCTION _glIsTexture~%% (BYVAL texture AS _UNSIGNED LONG)
  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.

SUB _GL _glBindTexture, _glDeleteTextures, _glGenTextures
