Learn the best practices for working with FFI::Platypus in Perl to interface with C libraries efficiently and safely.

When using FFI::Platypus to call C functions from Perl, there are several best practices to ensure robust and maintainable code.
Always use the correct data types when declaring your C functions. FFI::Platypus provides various type mappings that you should utilize to prevent runtime errors.
Implement error handling to catch and manage any issues that may arise from calling C functions. Check return values and handle exceptions gracefully.
Clearly document your code, especially the FFI::Platypus interface. Include details about the C functions you are interfacing with, their parameters, and return types.
Where possible, prefer using native libraries that are actively maintained and have good documentation. This will reduce potential issues associated with deprecated or poorly maintained libraries.
Write comprehensive tests for your FFI::Platypus interfaces to ensure that your Perl code interacts correctly with the C libraries.
use FFI::Platypus;
my $ffi = FFI::Platypus->new( api => 1 );
# Attach a C function `add` that takes two integers and returns an integer
$ffi->attach( add => [] => 'int' );
# Use the C function from Perl
my $result = add(2, 3);
print "The result is: $result\n"; # Outputs: The result is: 5
