Top Forums Programming getting the pid of another C program with unix calls Post 302407473 by Corona688 on Thursday 25th of March 2010 02:06:58 PM

system() does not work that way. it doesn't return text, it returns success or failure.

Since you're running a shell anyway by using system(), why not:

Code:
system("kill -INT `pidof -s client.c`");

Really though, this isn't a very good design. You won't be able to run more than one client on the system since the server will never be able to tell between them by name alone; and why does the server need to send them SIGINT anyway?

Net::Server::Log::Sys::Syslog(3)			User Contributed Perl Documentation			  Net::Server::Log::Sys::Syslog(3)

NAME
Net::Server::Log::Sys::Syslog - log via Syslog SYNOPSIS
use base qw(Net::Server::PreFork); __PACKAGE__->run( log_file => 'Sys::Syslog', syslog_ident => 'myapp', ); DESCRIPTION
This module provides Sys::Syslog logging to the Net::Server system. CONFIGURATION
log_file To begin using Sys::Syslog logging, simply set the Net::Server log_file configuration parameter to "Sys::Syslog". If the magic name "Sys::Syslog" is used, all logging will take place via the Sys::Syslog module. If syslog is used the parameters "syslog_logsock", "syslog_ident", and "syslog_logopt",and "syslog_facility" may also be defined. syslog_logsock Only available if "log_file" is equal to "Sys::Syslog". May be either unix, inet, native, console, stream, udp, or tcp, or an arrayref of the types to try. Default is "unix" if the version of Sys::Syslog < 0.15 - otherwise the default is to not call setlogsock. See Sys::Syslog. syslog_ident Only available if "log_file" is equal to "Sys::Syslog". Id to prepend on syslog entries. Default is "net_server". See Sys::Syslog. syslog_logopt Only available if "log_file" is equal to "Sys::Syslog". May be either zero or more of "pid","cons","ndelay","nowait". Default is "pid". See Sys::Syslog. syslog_facility Only available if "log_file" is equal to "Sys::Syslog". See Sys::Syslog and syslog. Default is "daemon". DEFAULT ARGUMENTS FOR Net::Server The following arguments are available in the default "Net::Server" or "Net::Server::Single" modules. (Other personalities may use additional parameters and may optionally not use parameters from the base class.) Key Value Default ## syslog parameters (if log_file eq Sys::Syslog) syslog_logsock (native|unix|inet|udp |tcp|stream|console) unix (on Sys::Syslog < 0.15) syslog_ident "identity" "net_server" syslog_logopt (cons|ndelay|nowait|pid) pid syslog_facility w+ daemon METHODS
"initialize" This method is called during the initilize_logging method of Net::Server. It returns a single code ref that will be stored under the log_function property of the Net::Server object. That code ref takes log_level and message as arguments and calls the initialized log4perl system. "handle_log_error" This method is called if the log_function fails for some reason. It is passed the Net::Server object, the error that occurred while logging and an arrayref containing the log level and the message. In turn, this calls the legacy Net::Server::handle_syslog_error method. LICENCE
