iofunc_sync_default()

Since:

BlackBerry 10.0.0

Arguments:

ctp

A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.

msg

A pointer to the io_sync_t structure that contains the message that the resource manager received. For more information, see iofunc_sync_verify().

ocb

A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The function iofunc_sync_default() function implements POSIX semantics for the client's sync() call, which is received as an _IO_SYNC message by the resource manager.

You can place this function directly into the io_funcs table passed to resmgr_attach(), at the sync position, or you can call iofunc_func_init() to initialize all of the functions to their default values.

The iofunc_sync_default() function calls iofunc_sync_verify() to see if the client can synchronize the resource.

Returns:

EINVAL

The resource doesn't support synchronizing.

EOK

The client can synchronize the resource.
