Hi Frank,
I've recompiled the files for Borland C environment for the
4.4.6 version. The code is now synchron with yours to set the
path I've implemented a new source file call pj_init1.c it is
very short and contains our discussed code to set the nad search
path via the "setfinder" function. I've have to do so, because
you can't set a function prototype through a DLL.
For the library I've to add only the function
PJ * pj_init_plus_path( const char *definition, const char *aDataPath )
to the proj_api.h and the proj.def file.
But I lost the feature to set the absolut path in the tools proj, nad
etc. May be it is usefull for this tool to establish a path switch ?
Bye Alex
The new library is initial tested for the Booland C++wrapper class and
the Delphi API. I' will send a mail if the files are downloadable.
Here the code for pj_init1.c

static char *ProjDataPath = NULL;

static const char *ProjFileFinder( const char *aFile )
{
static char *aLastPath = NULL;
if( ProjDataPath == NULL )
return aFile;
if( aLastPath != NULL )
free( aLastPath );
aLastPath = (char *) malloc(strlen(ProjDataPath)+strlen(aFile)+2);
strcpy( aLastPath, ProjDataPath );
strcat( aLastPath, "\\" );
strcat( aLastPath, aFile );
return aLastPath;
}
//---------------------------------------------------------------------------
PJ * pj_init_plus_path( const char *definition, const char *aDataPath )
{
if( aDataPath != NULL ) {
if( ProjDataPath != NULL )
free( ProjDataPath );
ProjDataPath = strdup(aDataPath);
}
pj_set_finder( ProjFileFinder );
return pj_init_plus(definition);
}
