Standard C Library (libc.so, libc.a)
unsigned int _getlong (
u_char *message_ptr );
Specifies a pointer into the byte stream.
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 information 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.
Upon successful completion, the _getlong() function returns an unsigned int (32-bit) value.
Defines name server and domain names.
