- GGeettppeeeerrnnaammee() returns the name of the peer connected to socket _s. The
- _n_a_m_e_l_e_n parameter should be initialized to indicate the amount of space
- pointed to by _n_a_m_e. On return it contains the actual size of the name re-
- turned (in bytes). The name is truncated if the buffer provided is too
- small.

-
