This structure contains the name and protocol numbers that correspond to a given protocol name. Applications must never attempt to modify this structure or to free anything inside the structure. Furthermore, only one copy of this structure is allocated per thread, and therefore, the application should copy any information it needs before issuing any other Windows Sockets function calls.

Syntax

struct protoent {
  char FAR* p_name;
  char FAR* FAR* p_aliases;
  short p_proto;
};

Members
