I want to know functions that are not memory leaks, buffer overflows, or thread safe.

[hitsato]

We, I am using nRF 5 SDK v 14.2.0.

Power-off has occurred during program development.
I can not identify the location,
Functions that are not memory leak, buffer overflow, thread safe
If you understand, it will be appreciated if you can tell me.

Thank you.

Hi.

I do not understand your question unfortunately.

Can you please explain more :-)

What example are you looking at?

Do you have any code you can show?

Best regards,

Andreas

Thank you for your reply.
There is no code that can be displayed.


As shown below, there is information "Thread-safe C library function" "C library function not thread-safe"
I would like to ask if there are other C library functions as well.

C library function not thread safe
infocenter.arm.com/.../index.jsp

Thread-safe C library functions
infocenter.arm.com/.../index.jsp

In addition, if you want to tell me if there is a C library function that can lead to memory leaks or buffer overflow
It means that.

Hi :-)

I can explain memory leak, buffer overflow, and thread safe for Nordic solutions (Nordic SDK) codesnippets if you post them here :-)

 All type of C code can be used wrong and cause memory leaks or buffer overflow.

Please post your code snippet :-)

Hi,
Thank you for your reply.
If it posts here, it is a program of several thousand steps, since it is mostly not developed by me, it can not be excerpted and posted.
I will post as soon as a suspicious place is found.
