_getlong(3)_getlong(3)NAME_getlong - Retrieves 32-bit quantities from a byte stream
SYNOPSIS
#include <sys/types.h> #include <netinet/in.h> #include
<arpa/nameser.h> #include <resolv.h>
unsigned int _getlong(
u_char *message_ptr );
LIBRARY
Standard C Library (libc)
PARAMETERS
Specifies a pointer into the byte stream.
DESCRIPTION
The _getlong() function gets 32-bit quantities from the byte stream or
arbitrary byte boundaries.
The _getlong() function is one of a set of subroutines that form the
resolver, a set of functions that resolves domain names. Global infor‐
mation that is used by the resolver functions is kept in the _res data
structure. The include/resolv.h file contains the _res data structure
definition.
RETURN VALUES
Upon successful completion, the _getlong() function returns an unsigned
int (32-bit) value.
FILES
Defines name server and domain names.
