Function Documentation

int findFdIndex ( sock_t fd )

Searches for a given socket fd in the handler table, fdTable, returning index or -1 if not found.
Searches fdTable for the given fd in the array. Returns index if found.
Parameters:

fd the fd to search for

Returns:
The index where fd is found, or -1 if not found
