I was trying to use one of the function defined in dpmi.h header. So I wrote that program:

#include <stdio.h>
#include <dpmi.h>

MemInfo_t mi;

void main()
{
if(dpmi_IsRealMode()) printf("Real mode\n");
else printf("non Real mode\n");

dpmi_GetFreeMemInfo(&mi);
printf("%lu\n", mi.LargestContiguousBlock);

}

but linker says:

D:\tmp>dmc -o sample1.exe -mx sample.c x32v.lib
link cx+sample,sample1,,x32v/noi;
OPTLINK (R) for Win32  Release 7.50B1

sample.obj(sample)
Error 42: Symbol Undefined _dpmi_GetFreeMemInfo
sample.obj(sample)
Error 42: Symbol Undefined _dpmi_IsRealMode

--- errorlevel 2

I did a search in lib subdirectory of dmc compiler and not found any *.lib containing those undefined functions. So, what additionaly I should link to my program?

Thanks in advance,

Did you get the files from www.dosextender.com?

Yes, I did. I took x32.zip file from ftp://ftp.dosextender.com/x32.zip

Those functions are only available under 16 bit Windows. Sorry.
