 void  _putlong(unsigned long long_integer,
                unsigned char *message_pointer)

The _putlong() function is used to put an unsigned long byte quantity into a byte stream.

Authorities and Locks

None.

Parameters

long_int

(Input) The 32-bit integer to be put into the byte stream.

unsigned char *message_pointer

(Input) The pointer to where the long_integer is to be put.

Return Value

_putlong() puts a 32-bit integer into message_pointer.

Usage Notes

DNS packets have fields that are unsigned long integers (for example, TTL and serial number). _putlong() is generally used to put these fields into a DNS packet.
