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.








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.
