(in Windows) PE file format contains Import table with
Module\Dll Name which tells PE loader where to search for symbol e.g.
KERNEL32.dll -> CreateFileW
In the ELF file format there is
Symbol table with
info field which tells if the symbol is
My question is how does the Unix loader know what is the module, shared object where to search for this symbol e.g.
???? -> snprintf
Could someone with more knowledge on ELF file format shed some light on Unix dynamic-linking?
