ham_action_fail_waitfor()

Add a waitfor action to an action, that will be executed if the corresponding action fails

Synopsis:

#include <ha/ham.h>

int ham_action_fail_waitfor(
                 ham_action_t *ahdl,
                 const char *aname, 
                 const char *path, 
                 int delay, 
                 unsigned flags);

Library:

libham

Description:

The ham_action_fail_waitfor() function adds an action fail item (aname) to the specified action. The action will either delay for delay milliseconds or wait until path (if specified) appears in the name space (whichever is earlier). The path parameter must contain the FULL path that is being watched for.

The handle (ahdl) is obtained either:

The action is executed when the corresponding action that it is associated with, fails.

Currently, there are no flags defined.

Returns:

0
Success.
-1
An error occurred (errno is set).

Errors:

EBADF
Couldn't connect to the HAM.
EINVAL
The name given in aname is invalid (e.g. it contains the / character) or is NULL.

The connection to the HAM is invalid. This happens when the process that opened the connection (using ham_connect()) and the process that's calling ham_action_execute() aren't the same.

ENAMETOOLONG
The name given (in aname) is too long, i.e. it exceeds _POSIX_PATH_MAX (defined in <limits.h>). Note that the combined length of an entity/condition/action name is also limited by _POSIX_PATH_MAX.
ENOENT
There's no entity or condition specified by the given handle (ahdl).
ENOMEM
Not enough memory to create a new handle.

In addition to the above errors, the HAM returns any error it encounters while servicing this request.

Classification:

QNX Neutrino

Safety:
Cancellation point No
Interrupt handler No
Signal handler No
