gcc warnings: implicit declaration of function...
I am having strange warnings from gcc compiler, which I don't think should come while cmpiling.
Can anyone help? The warnings are:
- warning: implicit declaration of function 'bzero'
- warning: implicit declaration of function 'inet_addr'

The code is as below:

int main(int argc, char **argv)
{
struct sockaddr_in servaddr;
char buffer[BUFLEN];
int n;

argv0 = argv[0];

if ( (sockfd=Socket(AF_INET,SOCK_STREAM,0)) < 0 )
exit(1);

bzero(&servaddr,sizeof(servaddr));
servaddr.sin_family = AF_INET;

if ( (servaddr.sin_addr.s_addr = inet_addr("131.170.24.42"))
== -1 ) {
fprintf(stderr,"%s : inet_addr failed, errno=%d\n",argv0,errno);
exit(1);
}

.......
.......
}

Perl::Critic::Policy::TestingAndDebugging::ProhibitNoWarUsersContributed Perl DoPerl::Critic::Policy::TestingAndDebugging::ProhibitNoWarnings(3pm)

NAME

       Perl::Critic::Policy::TestingAndDebugging::ProhibitNoWarnings - Prohibit various flavors of "no warnings".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       There are good reasons for disabling certain kinds of warnings.	But if you were wise enough to "use warnings" in the first place, then it
       doesn't make sense to disable them completely.  By default, any "no warnings" statement will violate this policy.  However, you can
       configure this Policy to allow certain types of warnings to be disabled (See "CONFIGURATION").  A bare "no warnings" statement will always
       raise a violation.

CONFIGURATION

       The permitted warning types can be configured via the "allow" option.  The value is a list of whitespace-delimited warning types that you
       want to be able to disable.  See perllexwarn for a list of possible warning types.  An example of this customization:

	   [TestingAndDebugging::ProhibitNoWarnings]
	   allow = uninitialized once

       If a true value is specified for the "allow_with_category_restriction" option, then any "no warnings" that restricts the set of warnings
       that are turned off will pass.

	   [TestingAndDebugging::ProhibitNoWarnings]
	   allow_with_category_restriction = 1
