|
|
// The buffer list is a double linked list of all buffers.
|
|
// Each buffer can be in one of these states:
|
|
// never loaded: BF_NEVERLOADED is set, only the file name is valid
|
|
// not loaded: b_ml.ml_mfp == NULL, no memfile allocated
|
|
// hidden: b_nwindows == 0, loaded but not displayed in a window
|
|
// normal: loaded and displayed in a window
|
|
//
|
|
// Instead of storing file names all over the place, each file name is
|
|
// stored in the buffer list. It can be referenced by a number.
|
|
//
|
|
// The current implementation remembers all file names ever used.
