If the memory 42object has been supplied to more than one kernel, this parameter 43identifies the kernel that is making the call. 44<p> 45<dt> <var>offset</var> 46<dd> 47[in scalar] 48The offset within the memory object. 49<p> 50<dt> <var>data</var> 51<dd> 52[in pointer to dynamic array of bytes] 53The data that has been modified 54while cached in physical memory. 55</dl> 56<h3>DESCRIPTION</h3> 57<p> 58A <strong>memory_object_data_initialize</strong> function is called 59as the result of a kernel 60message providing the default memory manager with initial data for a 61kernel-created memory object. If the memory manager already 62has supplied data (by a previous <strong>memory_object_data_initialize</strong> or 63<strong>memory_object_data_return</strong>), it 64should ignore this call. Otherwise, the call behaves the same as the 65<strong>memory_object_data_return</strong> call. 66<p> 67The kernel makes this call only to the default memory manager and only on 68temporary memory objects that it has created with 69<strong>memory_object_create</strong>. 70<h3>RETURN VALUES</h3> 71<p> 72Only generic errors apply. 73<h3>RELATED INFORMATION</h3> 74<p> 75Functions: 76<a href="memory_object_create.html"><strong>memory_object_create</strong></a>, 77<a href="memory_object_data_return.html"><strong>memory_object_data_return</strong></a>, 78<a href="MO_default_server.html"><strong>memory_object_default_server</strong></a>, 79<a href="SMO_default_server.html"><strong>seqnos_memory_object_default_server</strong></a>. 80
