OO / STL approach
Here's another way to do it - I barely tested it, but it looks like it works.

namespace cpp_stl_method
{
using namespace std;

#define whitespaces ((char*)" \f\v\r\n\t")
inline void ltrim(string& s,char* ws=whitespaces)
{
int fs=s.find_first_not_of(ws);
if ((fs!=string::npos) && (fs>0)) s.erase(0,fs);
}

inline void rpad(string&s, int n, char ch)
{
int l=n-s.size();
if (l>0) s.append(l,ch);
}

int main()
{
string test; test=" X";
cout<<"before :"<<test<<": ";
ltrim(test);
cout<<"After ltrim :"<<test<<": ";
rpad(test, 32, ' ');
cout<<"after rpad :"<<test<<":"<<endl;
return 0;
}
} // cpp_stl_method


int main()
{
// Cmethod::main(); // you can try the C method here and compare the results
cpp_stl_method::main();
}

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
