Yea, your code is wrong.

public plugin_natives( ) {
    register_native( "get_some_string", "_get_some_string" );
}

public _get_some_string( iPlugin, iParams ) {
    static const szStrings[ ][ ] = {
        "rawr", "hello", "i like cookies"
    };
    
    set_string( 1, szStrings[ random( sizeof( szStrings ) ) ], get_param( 2 ) );
    
    return 1;
}

native get_some_string( szString[ ], const iMaxLen );

// ---

new szString[ 32 ];
get_some_string( szString, 31 );
log_amx( "Some String: %s", szString );
