Function Documentation

PVFS_error PINT_client_io_cancel (  PVFS_sys_op_id  id  )

Cancels in progress I/O operations. Returns: 0 on success, -PVFS_error on failure.

Here is the call graph for this function:

PVFS_error PINT_client_state_machine_post (  PINT_smcb *  smcb, PVFS_sys_op_id *  op_id, void *  user_ptr )

Adds a state machine into the list of machines that are being actively serviced.

Here is the call graph for this function:

PVFS_error PINT_client_state_machine_test (  PVFS_sys_op_id  op_id, int *  error_code )

Checks for completion of a specific state machine. If specific state machine has not completed, progress is made on all posted state machines.

Here is the call graph for this function:

PVFS_error PINT_client_state_machine_testsome (  PVFS_sys_op_id *  op_id_array, int *  op_count, void **  user_ptr_array, int *  error_code_array, int  timeout_ms )

Checks completion of one or more state machines. If none of the state machines listed in op_id_array have completed, then progress is made on all posted state machines.

PVFS_error PINT_client_wait_internal (  PVFS_sys_op_id  op_id, const char *  in_op_str, int *  out_error, const char *  in_class_str )

Continually test on a specific state machine until it completes. This is what is called when PINT_sys_wait or PINT_mgmt_wait is used.

Here is the call graph for this function:

void PINT_sys_release (  PVFS_sys_op_id  op_id  )

Finds state machine referenced by op_id and releases resources associated with it.

Here is the call graph for this function:

void PINT_sys_release_smcb (  PINT_smcb *  smcb  )  [static]

releases resources associated with an smcb. Can be used both on immediate completion and asynchronous completion
