# CallLocalFunction

## Description

Calls a public function from the script in which it is used.

| Name | Description |
| --- | --- |
| const functionName\[\] | Public function's name. |
| const specifiers\[\] | Tag/format of each variable |
| OPEN\_MP\_TAGS:... | 'Indefinite' number of arguments of any tag |

## Returns

If the function exists, returns the same as the called function.

If the function does not exist, returns 0.

## Format Specifiers

| **Placeholder** | **Meaning** |
| --- | --- |
| `a` | Passes an array (the next placeholder should be d or i for the array size, so the function will be aware of it).  
  
**NOTE**: It accepts only one dimension, so a trick like sizeof (array) + sizeof (array) \* sizeof (array\[\]) for the array size would be needed to pass a 2D array. |
| `c` | Passes a single character. |
| `d`,`i` | Passes an integer (whole) number. |
| `x` | Passes a number in hexadecimal notation. |
| `f` | Passes a floating point number. |
| `s` | Passes a string. |

The values for the placeholders follow in the exact same order as parameters in the call.

## Examples

```c
forward publicFunc(number, Float:flt, const string[]);
public publicFunc(number, Float:flt, const string[])
{
    printf("Received integer %i, float %f, string %s", number, flt, string);
    return 1;
}

CallLocalFunction("publicFunc", "ifs", 420, 68.999999999, "Hello world");
```

## Notes

warning

CallLocalFunction crashes the server if it's passing an empty string. (Fixed in open.mp)
