It's in _sre.c, here:
SRE_MATCH(SRE_STATE* state, SRE_CODE* pattern, int level)
SRE_MATCH is a macro, and expands to either sre_match or sre_umatch,
depending on whether Unicode support is enabled. Note that _sre.c arranges
to compile itself *twice*, via its
This is to get both 8-bit and Unicode versions of the basic routines when
Unicode support is enabled.

Heh. Does *any* Python source code have a man page <wink>?

Sorry, no idea. Note that sre works on any object supporting the ill-fated
buffer interface. You may have a hard time figuring out that too. But,
e.g., it implies that re can search directly over an mmap'ed file (you don't
need to read the file into a string first).
