Purpose
Controls
component RAS characteristics.
Syntax
#include <sys/ras.h>
kerrno_t ras_path_control (
char * path,
ras_cmd_t command,
void * arg,
long argsize);
Description
The
ras_path_control kernel
service passes a command to the RAS component specified by the
path parameter.
Note: During
the ras_path_control process, callbacks to the registrant of
the component might be initiated for changes that the RAS infrastructure
makes to the component. The registrant should be aware of this for
locking purposes (for instance, the registrant should not be holding
any locks the callback needs).
