# globus\_callout\_activation(3)

Activation - Callback API Activation.

## NAME

globus\_callout\_activation - Activation

 \- Callback API Activation.

## SYNOPSIS

### Macros

\#define **GLOBUS\_CALLOUT\_MODULE**\

### Variables

globus\_module\_descriptor\_t **globus\_i\_callout\_module**\

## Detailed Description

Callback API Activation.

Globus Callout API uses standard Globus module activation and deactivation. Before any Globus Callout API functions are called, the following function must be called:

```
globus_module_activate(GLOBUS_CALLOUT_MODULE)
```

This function returns GLOBUS\_SUCCESS if Globus Callout API was successfully initialized, and you are therefore allowed to subsequently call Globus Callout API functions. Otherwise, an error code is returned, and Globus GSI Credential functions should not be subsequently called. This function may be called multiple times.

To deactivate Globus Callout API, the following function must be called:

```
globus_module_deactivate(GLOBUS_CALLOUT_MODULE)
```

This function should be called once for each time Globus Callout API was activated.
