Pointer function question

[yukkimi0100]

void changeToTen(int *ptr) {
    *ptr = 10;
}

Is it possible to do a similar function in NPC scripts? required of a generic function that receives a variable and changes the value of the received variable

In the default npc script commands, no, you cannot. global temporary variables ($@ prefix) are used for this exact purpose.
NPC 1: 

$@variable = 100;

NPC 2: 

mes "" + $@variable + ""; // this will output 100
