Hi
I want to extract variables values from a string buffer. Can anyone
pleease tell me how can i do that.
In C how to use perl like regular expressions.
Channel Location State Application(Data)

10 active channels
5 of 200 max active calls ( 2.50% of capacity)
I want to extract three numeric data fields from last line:
as
%d of %d max active calls ( %l% of capacity)
result : 5,200,2.50
means 2.5
Thanks and Regards
Jai

If you really want to use Perl style regular expressions, use libpcre (www.pcre.org). It will be available in your package manager, and probably already installed. If you don't need the full functionality of a regex, look into the scanf family of functions.

there are also POSIX regular expressions, bundled with the libc.
$ man regcomp or man regex (same)
this is highly portable, and already in libc. those RE are the same as
sed's expressions (except shell escapes are not needed).

this /RE/ should match the desired 3 numbers (inside parenthesis):
/^([0-9]*) of ([0-9]*) max .* ([0-9]*\.*[0-9]*)% of.*/
