Memory leaks in na_startup?

sistemasgmv — Thu, 05 Jun 2025 05:44:49 GMT

Hi all, I'm developing a little application in C using API version 5.1 and I use valgrind to detect memory leaks in my code. I have found a possible leak within the na_startup API call, just with the following code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include <locale.h>

#include <netapp_api.h>

int main(void)

{

char *StartupErrBuf;

StartupErrBuf=(char *)calloc(256,sizeof(char));

na_startup(StartupErrBuf,strlen(StartupErrBuf));

free(StartupErrBuf);

na_shutdown();

exit(1);

}

valgrind reports 41 allocs and only 21 frees. I'm not an expert developer but I guess there are some intermediate allocs which are not freed or maybe I'm doing something wrong.

This is part of the report from valgrind when it is used to analyze the compiled binary from the above code:

==31653== HEAP SUMMARY:

==31653== in use at exit: 268 bytes in 20 blocks

==31653== total heap usage: 40 allocs, 20 frees, 1,106 bytes allocated

==31653== by 0x4C17E15: na_startup (na.c:270)

Any help will be very appreciated.

Hi Eduardo,

As Sen said. We will look into the issue.

If it is indeed a memory leak, we will see if we can fix it in the upcoming releases of NMSDK.

Thank you for bringing this to our notice.
