PtGetStruct()

Retrieve the specified resource

Synopsis:

int PtGetStruct( char *base, 
                 PtResourceRec_t const *mod, 
                 PtArg_t *arg );

Arguments:

base

The base address in the widget from which to fetch the resource.

mod

The resource record for the resource.

arg

A pointer to a PtArg_t structure (see the Photon Library Reference) that describes the resource you want to retrieve. For more information, see below.

Description:

This function retrieves the resource specified by arg from the widget at address base as described by mod.

If the value and len members of arg are non-NULL, they're assumed to contain the addresses of pointers of the type appropriate for the resource. The pointers are set to point to the resource's value in the widget's internal memory.

---

Don't use these pointers to change the resource's value.

---

If either of the value and len members of arg is NULL, the retrieved resources are stored in these members.

Returns:

0

Successful completion.

-1

An error occurred.

Classification:
