| region | read | DMA region to write. |
| gfirst | read | First element of the DMA region to write. |
| gcount | read | Number of elements to write. |
| request | write | Request descriptor to hold the status. |
| format | read | Format of the data to send. |
| address | write | Address of the data to send. |
| count | read | Number of elements of the data to send. |
This function performs a blocking write to a specific DMA region region. It posts a request to write the remote data with its own format information, but starting at the element gfirst, with gcount elements. The data sent locally will be treated as count elements of the format and will be taken contiguously, starting at address.
On return of this function, the variable pointed by request contains an opaque request that can be used later to check the completion status of the operation.
| Error Code | Description |
A0ErrFailSend | It was not possible to send a request. | |
A0ErrInvFormat | The format has an invalid type. | |
A0ErrNotImplem | The format has an unimplemented type. | |
A0ErrOk| Successful completion. | |
