glDeleteBuffers

glDeleteBuffers is a function in the OpenGL graphics API used to delete one or more buffer objects. Buffer objects store various types of data, such as vertex data, texture data, or uniform data, that can be efficiently accessed by the GPU.

When a buffer object is no longer needed, it should be deleted to free up associated memory and resources. Calling glDeleteBuffers with the identifier of a buffer object marks it for deletion. The actual deletion occurs when the buffer is no longer bound to any target or in use by any Vertex Array Object (VAO).

The function takes two arguments: the number of buffer objects to delete and a pointer to an array containing the names (identifiers) of the buffer objects to be deleted. For example, to delete a single buffer named myBuffer, one would call glDeleteBuffers(1, &myBuffer). To delete multiple buffers, the count would be greater than one, and the array would hold the names of all buffers to be deleted.

It is important to note that calling glDeleteBuffers on a buffer object that has already been deleted or on a buffer name that was never generated results in no action being taken. However, it is good practice to ensure that buffer objects are only deleted once. After deletion, the buffer name becomes invalid and cannot be used for any subsequent buffer operations until it is regenerated using glGenBuffers.
