Search attributes in one structure using the values from another structure
Hello Groups
I am trying to find out ways of comparing a value from a 'c' structure to a value in another 'C' structure. the 'C' structure can be a List or liked list as it contains lot many records.
if we loop it in both the structures it is going to consume time.
I am looking for a simple algorithm where i can implement it easily.
For eg)
struct x
{
char empname[20] ;
int empno;
int deptno;
}x1;
struct y
{
char deptname[20];
int deptno;
}y1;
Structure x can be in a list where it contains say 1000 records and similaraly y.
I need to search the deptno of x in deptno of y.
Reply me if you have ideas.
Regards
Dhanamurthy

ares_parse_a_reply
ARES_PARSE_A_REPLY(3) Library Functions Manual ARES_PARSE_A_REPLY(3)
NAME
ares_parse_a_reply - Parse a reply to a DNS query of type A
SYNOPSIS
#include <ares.h>
int ares_parse_a_reply(const unsigned char *abuf, int alen,
struct hostent **host,
struct ares_addrttl *addrttls, int *naddrttls);
DESCRIPTION
The ares_parse_a_reply function parses the response to a query of type A into a struct hostent and/or an array of struct ares_addrttls.
The parameters abuf and alen give the contents of the response. The result is stored in allocated memory and a pointer to it stored into
the variable pointed to by host, if host is nonnull. It is the caller's responsibility to free the resulting host structure using
ares_free_hostent(3) when it is no longer needed.
If addrttls and naddrttls are both nonnull, then up to *naddrttls struct ares_addrttl records are stored in the array pointed to by addrt-
tls, and then *naddrttls is set to the number of records so stored. Note that the memory for these records is supplied by the caller.
RETURN VALUES
ares_parse_a_reply can return any of the following values:
ARES_SUCCESS The response was successfully parsed.
ARES_EBADRESP The response was malformatted.
ARES_ENODATA The response did not contain an answer to the query.
ARES_ENOMEM Memory was exhausted.
