pawn Code:

if(!strcmp(cmdtext, "/skin", true))
{
    new skinid ;
    tmp = strtok ( cmdtext , idx ) ;
    if ( !strlen ( tmp ) ) return SendClientMessage ( playerid, -1, "/skin [skin]" ) ;
    skinid = strval ( tmp ) ;
    if ( skinid < 0 || skinid > 300 ) return SendClientMessage ( playerid, -1, "Skin invalida" ) ;
    SetPlayerSkin ( playerid , skinid ) ;
    format ( string , sizeof ( string ) , "Skin %d" , skinid ) ;
    SendClientMessage ( playerid , -1 , string ) ;
    return 1 ;
}

E Use a Stock "strtok" :

pawn Code:

stock strtok(const string[], &index)
{
    new length = strlen(string);
    while ((index < length) && (string[index] <= ' '))
    {
        index++;
    }

    new offset = index;
    new result[20];
    while ((index < length) && (string[index] > ' ') && ((index - offset) < (sizeof(result) - 1)))
    {
        result[index - offset] = string[index];
        index++;
    }
    result[index - offset] = EOS;
    return result;
}
