I am trying to use the function snprintf() in the #include<stdio> library. However, when I build I find the function does not exist. When I open up the "stdio library" file, I see it is from 1986-1999 and that function does not exist.
However, I have another project where I also use the function snprintf() in the #include<stdio> library and I have no issue. When I open up the "stdio library" file, I see it is from 2003-2010 and the function exists.
How do I include the more recent library such that I can use this function?

Hey James,
You were right, I am using IAR version 7.12.1 and the problem was in the library configuration. The setting was originally CLIB and I should be using NORMAL DLIB to use the more updated library.
Thanks for the help,
Nice work! Thanks for letting the community know what helped solve the issue. I'll mark the thread as resolved.
Regards,
James
