The glDeleteTextures function deletes named textures.

Syntax

void WINAPI glDeleteTextures(
         GLsizei n,
   const GLuint  *textures
);

Parameters

n: The number of textures to be deleted.
textures: An array of textures to be deleted.

Return value

This function does not return a value.

Error codes

The following error codes can be retrieved by the glGetError function.

Name	Meaning
GL_INVALID_VALUE	n was a negative value.
GL_INVALID_OPERATION	The function was called between a call to glBegin and the corresponding call to glEnd.

Remarks

The glDeleteTextures function 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). The glDeleteTextures function ignores zeros and names that do not correspond to existing textures.

If a texture that is currently bound is deleted, the binding reverts to zero (the default texture).

You cannot include calls to glDeleteTextures in display lists.

Note

The glDeleteTextures function is only available in OpenGL version 1.1 or later.
