dpm_ping - check if Disk Pool Manager is alive and return its version number
#include <sys/types.h> #include "dpm_api.h" int dpm_ping (char *server, char *info)
dpm_ping checks if the Disk Pool Manager is alive and returns its version number.

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
EFAULT info is a NULL pointer. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. EDPMNACT Disk Pool Manager is not running or is being shutdown.
