sysevent_get_vendor_name, sysevent_get_pub_name, sysevent_get_pid - get
vendor name, publisher name or processor ID of event
SYNOPSIS
cc [flag ...] file ...-lsysevent [library ...]
#include <libsysevent.h>
char *sysevent_get_vendor_name(sysevent_t *ev);
char *sysevent_get_pub_name(sysevent_t *ev);
pid_t sysevent_get_pid(sysevent_t *ev);
PARAMETERS
ev handle to a system event object
DESCRIPTION
The sysevent_get_pub_name() function returns the publisher name for the
sysevent handle, ev. The publisher name identifies the name of the
publishing application or kernel subsystem of the sysevent.
The sysevent_get_pid() function returns the process ID for the publish‐
ing application or SE_KERN_PID for sysevents originating in the kernel.
The publisher name and PID are useful for implementing event acknowl‐
edgement.
The sysevent_get_vendor_name() function returns the vendor string for
the publishing application or kernel subsystem. A vendor string is the
company's stock symbol that provided the application or kernel subsys‐
tem that generated the system event. This information is useful for
filtering sysevents for one or more vendors.
The interface manages the allocation of the vendor and publisher name
strings, but it is the caller's responsibility to free the strings when
they are no longer needed by calling free(3MALLOC). If the new vendor
and publisher name strings cannot be created, sysevent_get_ven‐
dor_name() and sysevent_get_pub_name() return a null pointer and may
set errno to ENOMEM to indicate that the storage space available is
insufficient.
EXAMPLES
Example 1: Parse sysevent header information.
The following example parses sysevent header information from an appli‐
cation's event handler.
char *vendor;
char *pub;
void
event_handler(sysevent_t *ev)
{
if (strcmp(EC_PRIV, sysevent_get_class_name(ev)) != 0) {
return;
}
vendor = sysevent_get_vendor_name(ev);
if (strcmp("SUNW", vendor) != 0) {
free(vendor);
return;
}
pub = sysevent_get_pub_name(ev);
if (strcmp("test_daemon", pub) != 0) {
free(vendor);
free(pub);
return;
}
(void) kill(sysevent_get_pid(ev), SIGUSR1);
free(vendor);
free(pub);
}
