InternalLoadSeg

Low-level load function (V36)

Loads a load file from 'fh'. 'table' is used when loading an overlay, otherwise should be NULL. 'functionarray' is a pointer to an array of functions which will be used to read data and allocate/free memory as part of the load operation.

Note that the current Seek() position after loading may be at any point after the last hunk loaded. The FileHandle will not be closed. If a stacksize is encoded in the file, the size will be stuffed in the LONG pointed to by 'stack'. This LONG should be initialized to your default value: InternalLoadSeg() will not change it if no stacksize is found. Clears unused portions of Code and Data hunks (as well as BSS hunks). (This also applies to LoadSeg() and NewLoadSeg()).

If the file being loaded is an overlaid file, this will return -(seglist). All other results will be positive.

NOTE to overlay users: InternalLoadSeg() does NOT return seglist in both D0 and D1, as LoadSeg does. The current "ovs.asm" uses LoadSeg() and assumes returns are in D1. We will support this for LoadSeg() ONLY.

fh

Filehandle to load from.

table

When loading an overlay, otherwise ignored.

functionarray

Array of function to be used for read, alloc, and free.

FuncTable[0] -> Actual = ReadFunc(readhandle,buffer,length),DOSBase

D0 D1 A0 D0 A6

FuncTable[1] -> Memory = AllocFunc(size,flags), Execbase

D0 D0 D1 a6

FuncTable[2] -> FreeFunc(memory,size), Execbase

A1 D0 a6

stack

Pointer to storage (ULONG) for stacksize.

seglist

Seglist loaded or NULL. NOT returned in D1!

Really should use tags.
