How does strtok works?

I don't want to dig out the sources but i'd like to know how it implemented in C.

Use the source, Luke.

static variables

man strtok

Badly.

Terrible!

Advance the pointer past the leading whitespace. This is the pointer returned. Before returning, scan the string until encountering more whitespace or a NUL. Change this character to a NUL.

Just be aware that strtok in its traditional form uses static variables as >>4 mentioned and is thus non-reentrant. It's actually trivial to implement a reentrant strtok, though it would require you to pass in current state of tokenization on each function call

strtok considered unfunctional.
