NAME
- UnLoadSeg
-
Unload a seglist previously loaded by LoadSeg()
SYNOPSIS
success = UnLoadSeg( seglist )
D0 D1
BOOL UnLoadSeg(BPTR)
D0 D1
BOOL UnLoadSeg(BPTR)
FUNCTION
Unload a seglist loaded by LoadSeg(), which implies freeing memory and closing any open files used by the operating system for overlay management.
INPUTS
- seglist
-
BCPL pointer to a segment identifier; this may be NULL, in which case UnLoadSeg() does nothing.
RESULT
- success
-
returns 0 if a NULL seglist was passed or if it failed to close an overlay file
NOTES
UnLoadSeg() would return a random value before V36!
In case the segment contains at offset 8 the magic long word $ABCD (decimal: 43981), and the fourth longword after this identifier coincides with the global vector of the dos.library, the segment is identified as an overlay segment. UnLoadSeg() then releases addition resources such as the FileHandle for overlay management.
