ntohl()

Convert a 32-bit value from network-byte order to host-byte order

Synopsis:

#include <arpa/inet.h>

uint32_t ntohl( uint32_t netlong );

Arguments:

netlong
The value that you want to convert.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The ntohl() function converts a 32-bit value from network-byte order to host-byte order. If a machine's byte order is the same as the network order, this routine is defined as a null macro.

You most often use this routine in conjunction with internet addresses and ports returned by gethostbyname() and getservent().

Returns:

The value in host-byte order.

Classification:

POSIX 1003.1

Safety:
Cancellation point No
Interrupt handler Yes
