But sometimes I need to load a shared object and call the function.
In that case the function will be opened and prints messages (log messages) on the terminal.
Loading shared library using dlopen(),locating the function in so using dlsym and executing the function.
Here is the problem.
int (*abc)(int , int)
handle=dlopen("shareobject.so", RTLD_NOW);
abc =dlsym(handle,"fw");
//Executing function "fw" like
(*abc)(x,y)
In this case I need to capture the output only from the last statement.

mason::filters::standard
Mason::Filters::Standard(3pm) User Contributed Perl Documentation Mason::Filters::Standard(3pm)
NAME
Mason::Filters::Standard - Standard filters
DESCRIPTION
These filters are automatically composed into Mason::Component.
FILTERS
Capture ($ref)
Uses "$m->capture" to capture the content in $ref instead of outputting it.
% $.Capture(my $content) {{
<!-- this will end up in $content -->
% }}
... do something with $content
CompCall ($path, @args...)
Calls the component with path and @args, just as with "$m->scomp", with an additional coderef argument "yield" that can be invoked to
generate the content. Arguments passed to "yield" can be accessed inside the content via @_. This is the replacement for Mason 1's
Components With Content <http://search.cpan.org/perldoc?HTML::Mason::Devel#Component_Calls_with_Content>.
In index.mc:
% $.CompCall ('list_items.mi', items => @items) {{
<li><% $_[0] %></li>
% }}
In list_items.mi:
<%class>
has 'items';
has 'yield';
</%class>
% foreach my $item (@{$.items}) {
<% $.yield->($item) %>
% }
NoBlankLines
Remove lines with only whitespace from content. This
% $.NoBlankLines {{
hello
world
% }}
yields
hello
world
Repeat ($count)
Repeat the content block $count times. Note that the block is re-executed each time, which may result in different content.
<!-- Prints 1 to 5 -->
% my $i = 1;
% $.Repeat(5) {{
<% $i++ %><br>
% }}
Tee ($ref)
Uses "$m->capture" to capture the content in $ref, and also output it.
% $.Tee(my $content) {{
<!-- this will end up in $content and also be output -->
% }}
...
<!-- output content again down here -->
<% $content %>
Trim
Remove whitespace from the beginning and end of the content.
