glDeleteTextures deletes n textures named by the elements of the array textures. After a texture is deleted, it has no contents or dimensionality, and its name is free for reuse (for example by glGenTextures). If a texture that is currently bound is deleted, the binding reverts to 0 (the default texture).
glDeleteTextures silently ignores 0's and names that do not correspond to existing textures.
GL_INVALID_VALUE is generated if n is negative.
GL_INVALID_OPERATION is generated if glDeleteTextures is executed between the execution of glBegin and the corresponding execution of glEnd.
