Callback processing for das2 stream reads and writes. More...
Callback processing for das2 stream reads and writes.
These structure allow one to hook in Das2 Stream object processing that is triggered when Headers and Data are read or written to a file.

| typedef DasErrCode(* StreamDescHandler)(StreamDesc *sd, void *ud) |
Definition of the callback function invoked when a stream header is encountered in the input.
| sd | A pointer to the parsed StreamDesc |
| pd | A pointer to a user data structure, may be NULL. |
| typedef DasErrCode(* PktDescHandler)(StreamDesc *sd, PktDesc *pd, void *ud) |
Definition of the callback function invoked when a packet header is encountered in the input.
| sd | A pointer to the parsed Stream Descriptor |
| pd | A pointer to the parsed Packet Descriptor |
| ud | A pointer to a user data structure, may be NULL. |
| typedef DasErrCode(* PktRedefHandler)(StreamDesc *sd, PktDesc *pd, void *ud) |
Definition of the callback function invoked when a packet header is going to be deleted.
This only occurs if streams re-define packet IDs
| @param | sd A pointer to the parsed Stream Descriptor |
| pd | A pointer to the parsed Packet Descriptor |
| ud | A pointer to a user data structure, may be NULL. |
| typedef DasErrCode(* PktDataHandler)(PktDesc *pd, void *ud) |

Callback functions that invoked on Stream Close callback function that is called at the end of the stream.
| sd | A pointer to the parsed Stream Descriptor |

| typedef DasErrCode(* CommentHandler)(OobComment *se, void *ud) |
Callback functions that handle comments.
| se | A pointer to the parsed Comment |
