#Callout

Hello,

Hi,

I have a requirement to replace $ZF("%ZSET_DIR","/hold/rsm") to its equivalent Cache Class. The $ZF("%ZSET_DIR") sets the Current folder equivalent to "cd" command in Unix.

Can anyone help on this, please

Thanks & Regards,

I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.

I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.

How can I load a dll at run time using COS?

Does anyone have a good example of using %Net.SSH.Session to do a scp copy of a file from one server to another?

I have done Python - Cache binding setup following the guide from http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=.... I have also run test.py from sample3 folder and it able to run and complete successfully.

However, when I try to run the same test.py code via $zf, it gives error with exit code 1.

I've tried running help("intersys.pythonbind3") via $zf and also running from Cache terminal as follows:

Hello everybody,

We have a piece of Caché software which calls an external utility using $zf(-1,command). It works fine under Linux, but under Windows an external process occasionally hangs (due to some internal problems out of the scope here) and need to be killed programmatically. Having PID, it's easy to kill a process. If a Caché process is called with JOB command, the caller can easily get its PID from $zchild, but alas $zf(-1) does not seem to return the similar info. Is it possible to get it somehow?

I would like to invoke some unix/windows commands from COS, any API could do that?

Also, I would like to set up some Environment Variables for this process which would execute the above external command.

Anyway to achieve that?

Thanks for your help.

Hello,

I am trying to grab a specific zip file from a webpage but once I grab the zip file I need to grab a specific file within that zip file and I was hoping someone could explain how to do this or provide an example

I have a simple callout library:

#define ZF_DLL
#include 
#include 
#undef ERROR

int GetRandom(double* random) {
   // Py_Initialize();
   // Py_Finalize();
   *random = 1.0;
   return ZF_SUCCESS;
}

int main(int argc, char **argv)
{
   printf("Random: ");
   double random=0;
   GetRandom(&random);
   printf("%lf", random);
   return 0;
}

ZFBEGIN
    ZFENTRY("GetRandom","D",GetRandom)
ZFEND

I compile this code as a shared library and it works fine with:

I could launch a external process via $zf(-2).

However, this child process need to refer some shared libraries in RUNTIME,so I have to set up the proper paths to the environment variable LD_LIBRARY_PATH, is anyone know how to do this?

Thank for your help.

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

Thanks

I use zf(-2) to spawn a external a Java application in a *nix instance.

I would like to kill this process after some conditions met.

I would like to leverage $zf("kill ... ") but this requires its the pid of this child process.

So is there a way to acquire the pid for the child process when I create it ?

If not, how is the suggested way to kill this process?

Thanks.

I have a C string and I need to build a $lb from it.

This code works fine for strings shorter than 254 characters:

char *str = "some string";
int len = strlen(str);
int add = 2;
char *list = malloc(len + add + 1);
char lenChar = len + add;
sprintf(list, "%c\x01%s", lenChar, str);

Thought maybe someone can share the code for longer strings?
