You need "cygpath". You have system(). You know the full path to
cygwin1.dll (either you supplied it or via ::GetModuleFileName or
registry mount "/") so can replace the explicit path in the crude
example below with the proper one...
int
main(int argc, char *argv[])
{const char sfx[] ="j:/cygwin/bin/cygpath -wa ";
char cmd [MAX_PATH + sizeof(sfx) + 1];
if (argc < 2)
return EXIT_FAILURE
;
sprintf(cmd,"%s%s",sfx,argv[1]);
system(cmd);
return EXIT_SUCCESS; //ahem
}
...you'd probably want to programatically prefix your "j:/cygwin/bin" to
PATH prior to system(). If you go via the '-e' option of bash/sh then
you'd be able to use a wrapper script to convert more than one at once
or call your own cygwin app that invokes the relevent functions
directly.
