NAME
InternalLoadSeg -- Low-level load routine (V36)
SYNOPSIS
seglist = InternalLoadSeg(fh,table,functionarray,stack)
D0 D0 A0 A1 A2
BPTR InternalLoadSeg(BPTR,BPTR,LONG *,LONG *)FUNCTION
Loads from fh. Table is used when loading an overlay, otherwise should be NULL. Functionarray is a pointer to an array of functions. 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.
INPUTS
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.
RESULT seglist - Seglist loaded or NULL. NOT returned in D1!
BUGS Really should use tags.
