{{PageSyntax}}

  FUNCTION _glIsTexture~%% (BYVAL texture AS _UNSIGNED LONG)
  GLboolean '''_glIsTexture'''(GLuint {{Parameter|texture}});


; texture
: Specifies a value that may be the name of a texture.


{{PageDescription}}

'''_glIsTexture''' returns {{KW|_GL_TRUE}} if {{Parameter|texture}} is currently the name of a texture. If {{Parameter|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 {{KW|_GL_FALSE}}.

A name returned by {{KW|_glGenTextures}}, but not yet associated with a texture by calling {{KW|_glBindTexture}}, is not the name of a texture.
