FATS - Fast Access Tree System Table of Contents Programming Interfaces Turbo C, Borland C, C++ for DOS

Turbo C, Borland C, C++ for DOS

---

 
Needed Object Files

To link FATS to your programs you will need the following object modules:

fats.obj	The FATS module for DOS
fats_tcs.obj	interface / small-model
fats_tcm.obj	interface / medium-model
fats_tcc.obj	interface / compact-model
fats_tcl.obj	interface / large-model

The following libraries are included on the distribution diskette to call the FATS Workstation Engine:

fatstcsr.lib	interface / small-model
fatstcmr.lib	interface / medium-model
fatstccr.lib	interface / compact-model
fatstclr.lib	interface / large-model

If you want to make calls to the extended version of FATS (FATSXWE.EXE), you have to use the libraries fatsxcsr.lib (small), fatsxcmr.lib (medium), fatsxccr.lib (compact) or fatsxclr.lib (large).

 
Linking a Turbo C Program with FATS

To compile and link a application that calls FATS, use ONE of the following methods:

1. METHOD: Linking FATS to the program

BCC -m[?] tst1_eng.c fats.obj fats_tc[?].obj
[?] == s (small model), m (medium), c (compact), l (large)

2. METHOD: Calling the Workstation Engine (FATS_WE.EXE)

BCC -m[?] tst1_eng.c fatstc[?]r.lib

or if you own the extended version of FATS: (FATSXWE.EXE)

BCC -m[?] tst1_eng.c fatsxc[?]r.lib

 
Calling FATS

FATS commands are executed with the function FATSCALL:

unsigned long FATSCALL(char *szCmnd, unsigned short *nErrorcode, char *szFatsKey);

Parameter Usage:

szCmnd	Command string (input)
nErrorcode	Errorcode (output)
szFatsKey	Key value (output)
Return Value:	Record Number

 
Testprograms

The FATS distribution disk for PC-DOS/MS-DOS contains some test programs in the directory DOS_16I\C\BORLAND that illustrate how you can use the FATS commands in your programs:

tst1_eng.c	Test program for Turbo-C / Borland C
rebuild.c	Re-Indexing a Data File (commands 'BK', 'DL')

The extended version of FATS contains the following additional test programs:

tst2_eng.c	Introduction to the Matchcode Functions
mcsort.c	Use of the key-flag with command 'MC'
reindex.c	Fast Re-Indexing with the command 'XB'

 
Compatible Programming Interfaces

You also can use the interfaces provided by the FABS PLUS modules. Please take notice of the additional information at pages  4-77 and 9-77.

The following FABS interfaces are available:
