I have a bitcode file Y that has a symbol __isoc99_fscanf in it. When I disassemble the bitcode, the symbol is written as "\01__isoc99_fscanf". I am wondering where this symbol is coming from? I grep'ed throughout /usr on my machine for both names, and I only found __isoc99_fscanf, without the special character in front.
Regardless of where the symbol is coming from, I am trying to write a wrapper function in C, for each external function called in the bitcode file Y. By my own convention, the wrapper for a function f() is given the name f___xxxx___(). However, I can not seam to imitate the special character at the front of __isoc99_fscanf, when I'm writing the C code. Is there a way to do it, or do I need to revise my naming convention.
