MS-C, Quick 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_mcs.obj Interface / small-model fats_mcm.obj Interface / medium-model fats_mcc.obj Interface / compact-model fats_mcl.obj Interface / large-model
The following libraries are included on the distribution diskette to call the FATS Workstation Engine:
fatsmcsr.lib Interface / small-model fatsmcmr.lib Interface / medium-model fatsmccr.lib Interface / compact-model fatsmclr.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 MS-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
CL /c /A[?] /Ot tst1_eng.c
LINK tst1_eng fats.obj fats_mc[?].obj;
[?] == S (small model), M (medium), C (compact), L (large)
2. METHOD: Calling the Workstation Engine (FATS_WE.EXE)
CL /c /A[?] /Ot tst1_eng.c
LINK tst1_eng fatsmc[?]r.lib;or if you own the extended version of FATS: (FATSXWE.EXE)
LINK tst1_eng 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\MS that illustrate how you can use the FATS commands in your programs:
Test program for MS-C Compiler Re-Indexing a Data File (commands 'BK', 'DL')
The extended version of FATS contains the following additional test programs:
Introduction to the Matchcode Functions Use of the key-flag with command 'MC' 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:
FABS86 Exported from the object modules FATS_MCS.obj, FATS_MCM.obj and FATS_MCL.obj
