GlDeleteXxx

GlDeleteXxx is a group of functions used in the OpenGL API (Application Programming Interface) to manage object deletion. The functions are designed to release any resources associated with a particular object, including memory and other system resources.

The function name "GlDeleteXxx" is typically followed by a specific type of object that is being deleted. For example, GlDeleteTexture is used to delete a texture object, while GlDeleteBuffer is used to delete a buffer object. The suffix "Xxx" refers to the type of object being deleted.

When a GlDeleteXxx function is called, the input parameters are typically a reference to the object to be deleted. This reference is then removed, indicating to the OpenGL system that the object is no longer needed. If the object is the last reference to it, the GlDeleteXxx function will typically free any system resources associated with the object, including its memory.

If an object is deleted multiple times, it can lead to errors or crashes. This is because the GlDeleteXxx function does not actually delete the object, but rather signals the OpenGL system that it is no longer needed. If multiple references exist to an object, deletion through one reference will not delete the object if the other references remain.

Care should be taken when using GlDeleteXxx functions, as improper object deletion can result in memory leaks, crashes, or other system errors. Correct usage of these functions is essential in preventing such issues and ensuring proper program execution.
