You can run the command "ps -e | grep syslogd" and look at the first field in the returned string. That is the process ID for syslogd.

Also

pgrep syslogd

will work on Linux and Solaris (of recent vintage) ... cheers, drl

Hi.

So you wish to do what code in ps does. For that, note:

... ps works by reading the virtual files in /proc ...

-- excerpt from man ps

which suggests you should look at man proc.

Best wishes ... cheers, drl

No,
i wanted to write a programe for syslogd.pid , example,

#include<stdio.h>
int
main()
{
     printf("Hello World\n");
     return 0;
}

will print :- Hello World

like wise i want to write programe for syslogd.pid

Thanks,

Sorry, but I don't know if there is a specific function call that can get you information from /proc by name. Most people would pipe the output from the pgrep command to a temporary file and then use your C program to read the file and place the output into a variable.
