unsigned short NetShort;
The ntohs subroutine converts an unsigned short (16-bit) integer from Internet network byte order to the host byte order.
Receiving hosts require Internet addresses and ports in host byte order. Use the ntohs subroutine to convert Internet addresses and ports to the host integer representation.
The ntohs subroutine is defined in the net/nh.h file as a macro.
| NetShort | Requires a 16-bit integer in network standard byte order. |
The ntohs subroutine returns the supplied integer in host byte order.
The ntohs subroutine is part of Base Operating System (BOS) Runtime.
All applications containing the ntohs subroutine must be compiled with _BSD set to a specific value. Acceptable values are 43 and 44. In addition, all socket applications must include the BSD libbsd.a library.
