/* MAIN.C
|

|
|
|

|
|
Alternate, standalone main() file. Demonstrates
|
|||
|
|
linking to the startup code without having to link
|
|||
|
|
to any of the Turbo C library routines.

/*
|

|
|
|

|
|
Compile and link with:
|
|||
|
|
|
|||
|
|
tcc -c -ms main
|
|||
|
|
masm c0 /D__SMALL__ /D__NOFLOAT /t/mx;
|
|||
|
|
masm setargv /D__SMALL__ /t/mx;
|
|||
|
|
tlink c0 main setargv /c/m,main
|
|||
|
|
|
|||
|
|
For another memory model, replace __SMALL__ with one of
|
|||
|
|
__MEDIUM__, __COMPACT__, __LARGE__, __HUGE__
|
|||
|
|
|
|||
|
|
If using tiny model, replace __SMALL__ with __TINY__ and run
|
|||
|
|
exe2bin main.exe main.com
|
|||
|
|
del main.exe
|
|||
|
|
|
|||
|
|
Resulting main.exe has no references to the library.
|
|||
|
|
Caution: This example works only with no floating point code.
