These functions shall convert 16-bit and 32-bit quantities between network byte
order and host byte order.
On some implementations, these functions are defined as macros.
The
uint32_t and
uint16_t types are defined in
<inttypes.h>.
The
htonl() and
htons() functions shall return the argument value
converted from host to network byte order.
The
ntohl() and
ntohs() functions shall return the argument value
converted from network to host byte order.
No errors are defined.
The following sections are informative.
None.
These functions are most often used in conjunction with IPv4 addresses and ports
as returned by
gethostent() and
getservent().
None.
