How does the linker resolve symbols?

Hello,

How does the linker make the exact link between the contents of the header file and a library function it needs? in other words, if I include, say, <string.h>, how does the linker know which library to refer to, or maybe it scans all the available ones?

Thanks

Linkers don't know anything about header files, those are for the compiler. Normally, linkers scan standard libraries automatically.

plus any specific library(ies) that you specify on the command line (or in your IDE project options).

There may also be an otion to scan folders for libraries...
