General description
The ntohl()
function translates a long integer from network byte order to host
byte order.
- Parameter
- Description
- a
- The unsigned long integer to be put into host byte order.
- in_addr_t netlong
- Is typed to the unsigned long integer to be put into host byte order.
Notes:
- 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.
Returned value
ntohl() returns the translated long integer.
