If you want to make calls to the extended version of FATS, you have to choose fatsx.obj instead of fats.obj.
Linking a MS-C Program with FATS
To compile and link a application that calls FATS, use the following commands:
CL /Lp /A[?] /Ot tst1_eng.c fats.obj fats_mc[?].obj
[?] == S (small model), M (medium), C (compact), L (large)
or if you own the extended version of FATS:
CL /Lp /A[?] /Ot tst1_eng.c fatsx.obj fats_mc[?].obj
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 OS/2 contains some test programs in the directory OS2_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'
