[Konstantinos]

I do use packed strings and I had to reset the string for something I was making. I tried to use EOS ('\0') but it seems that it doesn't make the packed string NULL.

I run this code (here: http://slice-vps.nl:7070/#):

pawn Код:

#include <a_samp>

#if !defined isnull
    #define isnull(%1) \
        ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))
#endif

static stock
    Player_Name[MAX_PLAYERS][MAX_PLAYER_NAME char];
    
main()
{
    strpack(Player_Name[0], "Konstantinos", MAX_PLAYER_NAME);
    SetTimer("PrintName", 1000, false);
}

forward PrintName();
public PrintName()
{
    new
        sz_T[MAX_PLAYER_NAME];
    
    strunpack(sz_T, Player_Name[0], MAX_PLAYER_NAME);
    printf("Player_Name: \"%s\" -> %s", sz_T, (isnull(sz_T)) ? ("NULL") : ("NOT NULL"));
    Player_Name[0]{0} = EOS;
    SetTimer("PrintName2", 1000, false);
}

forward PrintName2();
public PrintName2()
{
    new
        sz_T[MAX_PLAYER_NAME];
    
    strunpack(sz_T, Player_Name[0], MAX_PLAYER_NAME);
    printf("Player_Name: \"%s\" -> %s", sz_T, (isnull(sz_T)) ? ("NULL") : ("NOT NULL"));
}

The output was:

pawn Код:

Player_Name: "Konstantinos" -> NOT NULL
Player_Name: "sts" -> NOT NULL

I then used:

pawn Код:

#include <a_samp>

#if !defined isnull
    #define isnull(%1) \
        ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))
#endif

static stock
    Player_Name[MAX_PLAYERS][MAX_PLAYER_NAME char];
    
main()
{
    strpack(Player_Name[0], "Konstantinos", MAX_PLAYER_NAME);
    SetTimer("PrintName", 1000, false);
}

forward PrintName();
public PrintName()
{
    new
        sz_T[MAX_PLAYER_NAME];
    
    strunpack(sz_T, Player_Name[0], MAX_PLAYER_NAME);
    printf("Player_Name: \"%s\" -> %s", sz_T, (isnull(sz_T)) ? ("NULL") : ("NOT NULL"));
    strpack(Player_Name[0], "\0", MAX_PLAYER_NAME);
    SetTimer("PrintName2", 1000, false);
}

forward PrintName2();
public PrintName2()
{
    new
        sz_T[MAX_PLAYER_NAME];
    
    strunpack(sz_T, Player_Name[0], MAX_PLAYER_NAME);
    printf("Player_Name: \"%s\" -> %s", sz_T, (isnull(sz_T)) ? ("NULL") : ("NOT NULL"));
}

And the output was:

pawn Код:

Player_Name: "Konstantinos" -> NOT NULL
Player_Name: "" -> NULL

It is NULL like I wanted to but is it the correct way of resseting a packed string?
