<h2>memory_object_synchronize_completed</h2>

<strong>Function</strong> - Inform the kernel that synchronized data has been processed.

<h3>SYNOPSIS</h3>

<strong>kern_return_t memory_object_synchronize_completed </strong>

<strong>(memory_object_control_t</strong> <var>memory_control</var>,

<strong>vm_offset_t</strong> <var>offset</var>,

<strong>vm_offset_t</strong> <var>length</var><strong>);</strong>

<h3>PARAMETERS</h3>

<dt> <var>memory_control</var>

[in memory-cache-control send right]

The memory cache control port

to be used by the memory manager for cache management requests.

This port is provided by the kernel in a <strong>memory_object_init</strong> call.

<dt> <var>offset</var>

[in scalar]

The offset within the memory object, in bytes.

<dt> <var>length</var>

[in scalar]

The amount of data processed. The number must be an

integral number of memory object pages.

<h3>DESCRIPTION</h3>

The <strong>memory_object_synchronize_completed</strong> function informs the kernel

that previously synchronized data (<strong>memory_object_synchronize</strong>)

has been queued or placed on backing storage. This reply causes the issuing

client to return from its <strong>vm_msync</strong> call. The offset and length

must match that of the corresponding <strong>memory_object_synchronize</strong>

call. There may be multiple synchronize requests

for a given memory object outstanding but they will not overlap.

<h3>RETURN VALUES</h3>

Only generic errors apply.
