/* impl.c.mpsliban: RAVENBROOK MEMORY POOL SYSTEM LIBRARY INTERFACE (ANSI)
|
|
*
|
|
* $Id$
|
|
* Copyright (c) 2001 Ravenbrook Limited.
|
|
*
|
|
* .purpose: The purpose of this code is
|
|
* 1. to connect the MPS Library Interface to the ANSI C libraries,
|
|
* where they exist, and
|
|
* 2. to provide an example of how to implement the MPS Library
|
|
* Interface.
|
|
*
|
|
* .readership: For MPS client application developers and MPS developers.
|
|
* .sources: design.mps.lib
|
|
*
|
|
*
|
|
* TRANSGRESSIONS (rule.impl.trans)
|
|
*
|
|
* .trans.file: The ANSI standard says (in section 7.9.1) that FILE is an
|
|
* object type, and hence the casts between FILE and mps_lib_FILE (an
|
|
* incomplete type) are not necessarily valid. We assume that this trick
|
|
* works, however, in all current environments.
