That is why i put "(not really)" behind that statement... I know they are not the real pointers.

Your question about freeing the allocated string is a good one, I'd also like to know the answer even though I'm almost sure it's not possible.

[bibu]

I attempted again a test, failed...
Didn't test it with allocating strings though and I also couldn't get it to work with the param_convert native.

PHP Code:

public plugin_natives()
{
    register_native("get_user_pmessage", "native_get_user_pmessage")
}

public native_get_user_pmessage(id, szBuffer[], iLen)
{
    new szBuffer[ 32 ]
//testing purpose
    get_user_name( id, szBuffer, 31)
    return szBuffer
}

/* *******

Other plugin

*/ *******

    new szPMsg[32]
    get_user_pmessage(id, szPMsg, 31)
    
    //param_convert(2); // 2 being the parameter number. 
    
    client_print(id, print_chat, "PMsg: %s", szPMsg) 


Empty string..

You have 2 variables named szBuffer.
Also the style doesn't match the parameter types.

Well, if it is not possible, I guess we need to make an AMXX module that will provide a native that can release a memory with a given offset(or whatever the value returned by EngFunc_AllocString is).

[Backstabnoob]

PHP Code:

public plugin_natives()
{
    register_native("get_user_pmessage", "native_get_user_pmessage")
}

public native_get_user_pmessage( iPlugin, iParams )
{
    new szBuffer[ 32 ]
//testing purpose
    get_user_name( get_param( 1 ), szBuffer, 31)
    return szBuffer
}


/* *******

Other plugin

*/ *******

client_print(id, print_chat, "PMsg: %s", get_user_pmessage( id ) ) 


Try this

You have to use the set_string() function (also you shouldn't return the string). I do it in Polymorph, check it out for an example.

[Backstabnoob]

I know how set_string works, I just thought this method might work with natives as well, but it doesn't seem it does.

This works:

PHP Code:

public plugin_init( )
{
    
    log_amx( "Server name is %s.", testfunc( ) )
}


testfunc( )
{
    new szServerName[ 32 ]
    get_user_name( 0, szServerName, charsmax( szServerName ) )
    
    return szServerName
} 


Output:

L 06/13/2014 - 01:21:58: [get_string.amxx] Server name is Half-Life dedicated server.

This doesn't:

Spoiler

Plugin 1:

PHP Code:

#include < amxmodx >


public plugin_natives( )
{
    register_native( "get_test_string", "_get_test_string" )
}

public _get_test_string( iPlugin, iParams )
{
    new szServerName[ 32 ]
    get_user_name( 0, szServerName, charsmax( szServerName ) )
    
    return szServerName
} 


Plugin 2:

PHP Code:

#include < amxmodx >


native get_test_string( )


public plugin_init( )
{
    log_amx( "Server name is %s.", get_test_string( ) )
} 


Output:

L 06/13/2014 - 01:20:49: [get_string.amxx] Server name is *********)x***************************

Edit:
I was just experimenting, don't take my posts in this thread too seriously. @bibu: You should of course use set_string because that's the most reliable and readable option.

[hornet]

Natives work differently.

Assuming your trying to set the length yourself bibu, then do so like in the following. If not, remove the param, and return set_string() / get_user_name().

Registered as per usual:

#include <amxmodx>

public plugin_natives()
{
    register_native( "get_user_pmessage", "_get_user_pmessage" );
}

public _get_user_pmessage()
{
    new iLen = get_param( 2 );
    
    new szName[ 32 ];
    get_user_name( get_param( 1 ), szName, iLen );
    
    set_string( 2, szName, iLen );
}

Registered with style 1:

#include <amxmodx>

public plugin_natives()
{
    register_native( "get_user_pmessage2", "_get_user_pmessage2", 1 );
}

public _get_user_pmessage2( id, szName[], iLen )
{
    param_convert( 2 );
    get_user_name( id, szName, iLen );
}

native get_user_pmessage( id, szName[], iLen );
native get_user_pmessage2( id, szName[], iLen );
