Members detail
This macro is declared in upipe/uprobe_transfer.h source file, line 41.
This macro is declared in upipe/uprobe_transfer.h source file, line 31.
This struct is declared in upipe/uprobe_transfer.h source file, line 58.
This struct is a super-set of the uprobe structure with additional local members.
int uprobe_xfer_add(struct uprobe *uprobe, enum uprobe_xfer_event xfer_event, int event, uint32_t signature)
This function is declared in upipe/uprobe_transfer.h source file, line 99.
This function allocates a sub-structure to transfer an event.
Parameter list:
- uprobe: pointer to probe
- xfer_event: type of the event
- event: event to be transferred
- signature: event signature, or 0 for standard events
The return value is an error code
This function is declared in upipe/uprobe_transfer.h source file, line 88.
This function allocates a new uprobe_xfer structure.
Parameter list:
- next: next probe to test if this one doesn't catch the event
The return value is pointer to uprobe, or NULL in case of error
void uprobe_xfer_clean(struct uprobe_xfer *uprobe_xfer)
This function is declared in upipe/uprobe_transfer.h source file, line 81.
This function cleans a uprobe_xfer structure.
Parameter list:
- uprobe_xfer: structure to clean
This enum is declared in upipe/uprobe_transfer.h source file, line 45.

| Identifier | Value | Description |
|---|---|---|
| UPROBE_XFER_SENTINEL | UPROBE_LOCAL+UPROBE_LOCAL | |
| UPROBE_XFER_VOID | unknown | a void event needs to be transferred |
| UPROBE_XFER_UINT64_T | unknown | a uint64_t event needs to be transferred |

struct uprobe * uprobe_xfer_init(struct uprobe_xfer *uprobe_xfer, struct uprobe *next)
This function is declared in upipe/uprobe_transfer.h source file, line 75.
This function initializes an already allocated uprobe_xfer structure.
Parameter list:
- uprobe_xfer: pointer to the already allocated structure
- next: next probe to test if this one doesn't catch the event
The return value is pointer to uprobe, or NULL in case of error

This function is for internal use only.
This function is declared in UPROBE_HELPER_UPROBE function like macro expansion, line 9 in upipe/uprobe_transfer.h source file, line 66.
This function returns the public uprobe structure.
Parameter list:
- uprobe_xfer: pointer to the private uprobe_xfer structure
The return value is pointer to the public uprobe structure
