# TAU\_SET\_INTERRUPT\_INTERVAL(3)

Change the inter-interrupt interval for tracking memory and headroom

## NAME

TAU\_SET\_INTERRUPT\_INTERVAL - Change the inter-interrupt interval for tracking memory and headroom

## SYNOPSIS

**C/C++:**

**TAU\_SET\_INTERRUPT\_INTERVAL(int** *value***);**

**Fortran:**

**TAU\_SET\_INTERRUPT\_INTERVAL(integer** *value***);**

## DESCRIPTION

Set the interrupt interval for tracking memory and headroom (See [TAU\_TRACK\_MEMORY(3)](/TAU_TRACK_MEMORY/3.md) and [TAU\_TRACK\_MEMORY\_HEADROOM(3)](/TAU_TRACK_MEMORY_HEADROOM/3.md)). By default an inter-interrupt interval of 10 seconds is used in TAU. This call allows the user to set it to a different value specified by the argument value.

## EXAMPLE

**C/C++ :**

```
TAU_SET_INTERRUPT_INTERVAL(2)
/* invokes the interrupt handler for memory every 2s */
```

**Fortran :**

```
call TAU_SET_INTERRUPT_INTERVAL(2)
```
