cm_end_trans(D3)

cm_end_trans -- complete a resource manager transaction

Synopsis

   #include <sys/types.h>
   #include <sys/confmgr.h>
   #include <sys/ddi.h>
   
   void cm_end_trans(rm_key_t key);

Description

cm_end_trans( ) completes a resource manager transaction that was started with cm_begin_trans(D3) or cm_newkey(D3). After cm_end_trans( ) executes, changes made during the transaction become visible to other contexts.

Arguments

key: identifies the resource manager record that has been accessed.

Return values

None

Usage

Modifications made to the resource manager database do not become effective until after cm_end_trans( ) executes successfully. Use the cm_abort_trans(D3) function to abort a transaction if necessary.

Context and synchronization

User or blockable context.

Hardware applicability

All

Version applicability

ddi: 8, 8mp

Differences between versions

In DDI versions prior to version 8, cm_begin_trans(D3) and cm_end_trans(D3) are not supported. Calls to functions that access the resource manager database are only atomic with respect to other simultaneous resource manager database accesses.
