c - How to get the length of a function in bytes?

Question

I want to know the length of C function (written by me) at runtime. Any method to get it? It seems sizeof doesn't work here.

Answer 1

There is a way to determine the size of a function. The command is:

 nm -S <object_file_name>

This will return the sizes of each function inside the object file. Consult the manual pages in the GNU using 'man nm' to gather more information on this.
