PARAMETERS

netintSpecifies a 32-bit integer in network-byte order. 

DESCRIPTION

The ntohl() (network-to-host long) function converts an unsigned 32-bit integer from Internet network-byte order to host-byte order. 

The Internet network requires address and port reference data in network-byte order.  You can use the ntohl() function to convert Internet network address and port data to host byte-ordered integers. 

RETURN VALUES

The ntohl() function returns a 32-bit integer in host-byte order. 

ERRORS

Current industry standards do not define error values for the ntohl() function.
