[PD-dev] Getting path of external

[Thomas Mayer]

Hi,

for PuREST JSON on Windows, I need a way to verify SSL signatures,
because currently this is not working. One way to accomplish that, is
setting the path to the certificate file. As I want to package the file
with the zip, I would like to store it in the same directory as the dll
for the externals.

I have two externals [rest] and [oauth] that share all the code for
libcurl, threading etc. (via a struct), so in the function where I need
to set the path to the certificate file, I need to get the path of the
dll to set the certificate store correctly.

Both classes are created by functions like:

rest_class = class_new(gensym(rest), (t_newmethod)rest_new,
(t_method)rest_free, sizeof(t_rest), 0,
A_GIMME, 0);

and

t_rest *x = (t_rest *)pd_new(rest_class);

Now, I need a way to get the value rest from this *x, for this:

static void *ctw_exec_req(void *thread_args) {
struct _ctw *common = thread_args;

/* more declarations */

#ifdef _WIN32
/* Workaround for loading certificates on Windows */
char path[2048];
/* This will output the path to pd.exe */
GetModuleFileName(NULL, path, 2048);
post(dll path: %s, path);
/* This will output the path to rest.dll, how do I get rest
from *thread_args */
GetModuleFileName(GetModuleHandle(rest), path, 2048);
post(dll path: %s, path);
#endif

/* all the rest to execute request via curl */
}


Thanks in advance,
Thomas

Re: [PD-dev] Getting path of external

[Hans-Christoph Steiner]

I think you want c_externdir, i.e.

rest_class-c_externdir-s_name,

That's the directory that the external was loaded from.  You'll need to
#include m_imp.h.  See externals/hcs/cursor.c for an example.
