What are Htons used for?

The htons() function translates a short integer from host byte order to network byte order. The unsigned short integer to be put into network byte order. Is typed to the unsigned short integer to be put into network byte order.

What is Htons and Ntohs?

The htons() function converts the unsigned short integer hostshort from host byte order to network byte order. The ntohs() function converts the unsigned short integer netshort from network byte order to host byte order.

Where is Htons defined?

The htons macro is defined in the h> header file.

What is Ntohl?

The ntohl() function translates a long integer from network byte order to host byte order. For MVS™, host byte order and network byte order are the same. Since this function is implemented as a macro, you need one of the feature test macros and the inet header file.

How does the htons function in Win32 work?

The htons function takes a 16-bit number in host byte order and returns a 16-bit number in network byte order used in TCP/IP networks (the AF_INET or AF_INET6 address family). The htons function can be used to convert an IP port number in host byte order to the IP port number in network byte order.

What does htons ( ) do in Linux programing?

According Linux manual The htons() function converts the unsigned short integer hostshort from host byte order to network byte order. The INADDR_* constants are local byte order and also must be swapped to network order using htonl (not htons), as in htonl(INADDR_ANY).

How does the htons function in socket programing work?

0x89 0x13. The htons() function makes sure that numbers are stored in memory in network byte order, which is with the most significant byte first. It will therefore swap the bytes making up the number so that in memory the bytes will be stored in the order.

What is the purpose of the htons function?

the htons() function converts values between host and network byte orders. There is a difference between big-endian and little-endian and network byte order depending on your machine and network protocol in use. It is done to maintain the arrangement of bytes which is sent in the network(Endianness).
