porting from c++ to C and some questions

hello

I am trying to port from C++ to C and I faced some problem.

The first problem is on how to port map things

for example:

Code:

---

static map<noor, water> category;

---

this in c++ how to port this in C?

Also, I found some thing like

Code:

---

bool static IsFromMe(water& aa)

---

what does this & mean?

Also

what does this sign mean? ( ::)

Code:

---

bool CTransaction::ReadFromDisk(CTxDB& txdb, COutPoint prevout, CTxIndex& txindexRet)

---

Thanks

Do you really need to port from C++ to C, or can you just use the C++ version, or implement directly in C?

Based on your questions, to do a port from C++ to C, you need to learn C++.
