It provides routinesto initialize the group, and to access the group scalar variables. For abroader description of MIB-II services, see the manual entry for m2Lib.To use this feature, include the following component:INCLUDE_MIB2_ICMPUSING THIS LIBRARYThis library can be initialized and deleted by calling the routinesm2IcmpInit() and m2IcmpDelete() respectively, if only the ICMP group's servicesare needed.  If full MIB-II support is used, this group and all othergroups can be initialized and deleted by calling m2Init() andm2Delete().The group scalar variables are accessed by callingm2IcmpGroupInfoGet() as follows:.CS    M2_ICMP   icmpVars;    if (m2IcmpGroupInfoGet (&icmpVars) == OK)	/@ values in icmpVars are valid @/.CEINCLUDE FILES: m2Lib.h SEE ALSO:m2Lib, m2IfLib, m2IpLib, m2TcpLib, m2SysLib*//* includes */#include <vxWorks.h>#include "m2Lib.h"#include <netinet/in.h>#include <netinet/in_systm.h>#include <netinet/ip.h>#include <netinet/ip_icmp.h>#include <netinet/icmp_var.h>#include "errnoLib.h"#include "semLib.h"#ifdef VIRTUAL_STACK#include "netinet/vsLib.h"#endif /* VIRTUAL_STACK *//* external declarations */#ifndef VIRTUAL_STACKextern struct icmpstat    icmpstat;   	/* ICMP statistics structure */#endif /* VIRTUAL_STACK *//********************************************************************************* m2IcmpInit - initialize MIB-II ICMP-group access** This routine allocates the resources needed to allow access to the MIB-II* ICMP-group variables.
