MPW 3.2 Toolbox Interfaces And Libraries

® Macintosh®Programmer's Workshop Toolbox Interfaces and Libraries Version 7.0 M0615LUB 030-B0 16-A 030-3622-A MPW 3.2 Libraries/Interfaces Release Notes Libraries Changes to the libraries since MPW 3.0 include the elimination of CInterface.o and CRuntime.o, their functionality having been merged into Interface.o and Runtime.o. The libraries have been resegmented so as to reduce the number of modules in segment "main". The MPW 3.2 C libraries conform to the current ANSI C standard. A number of modifications and additions have been made to the set of library functions, including new C-like string functions for Pascal strings and a C function for setting the type and creator on any file. A new library provides for the creating of applications that use a simple text I/O window to display and read console I/O (SlOW). For details, see the MPW 3.2 Simple Input/Output Window Release Notes. Linking Requirements The library CLib881.0 has a new positioning requirement as a consequence of the elimination of CRuntime.o. CLib881.0 must now not only precede all members of {CLibraries} in the link sequence but must also precede the library Runtime.o. Note that XCMDs for Hypercard require linking into one segment. Because of the new segmentation of the library, this will no longer happen automatically. This requirement can be met by putting the option -sg main on the link: command line to force the library routines and your code into a single segment.

The goal of changing the segmentation is to minimize the number of modules in the segment "Main". This way, if the user needs the space in "Main" for his application or tool, he has it. If he is more concerned about speed, the user can then manipulate his makefile to contain whatever he needs in his "Main" segment. • Segment layout LIBRARY Runtlme.o Se&ment Contents MAIN %A5Init INTENV Initialization and exit procedures, 32 bit math operations A5 initialization code, _DataInit, Module #000 1 Low level IOPort functions and I/O which directly calls those functions - done for pc relative offsets Device drivers <.S.tand Alone Devices) SADEV LIBRARY Pasllb.o SelWlent Contents MAIN INTENV Compiler initializations (the functions call Runtime.o) I/O which directly calls segment INTENV in Runtime.o (may change in the future) Pascal language I/O Heap, strings and math functions SIDIO PASLIB LIBRARY StdCLlb.o Contents SIDIO SIDCLm MPW 3.2 LibrarieslInterfaces Release Notes C language I/O All ANSI functions (except I/O) 2 Copyright Apple Computer, Inc. 1990-1991.
