System and Other Functions$ZUTIL(114,0) returns a null string, rather than an ethernet address if:• The primary ethernet device is not present in the device names list. $ZUTIL(114,0,name)returns a null string if the named device is not present in the device names list, or has nocorresponding ethernet address.• On Windows systems, the InterSystems Packet Driver is not installed.• On IBM AIX systems, the DLPI (Data Link Provider Interface) packages are not installed.• The ethernet adapters are protected against access by non-root users, and the processinvoking $ZUTIL(114,0) is not the root user.$ZUTIL(114,1) returns the current list of attached ethernet device names, delimited by$CHAR(1). The first name in this list is the primary ethernet device.$ZUTIL(114,2) returns the current list of ethernet device names, delimited by commas.$ZUTIL(114,2,name) replaces the current ethernet device names list with the list specifiedin name; it then returns the ethernet device names list prior to the replacement.ParametersflagThe switch that specifies the information that $ZUTIL(114) is to return. Valid values are:Code012DescriptionReturns the address of an attached ethernet device. When name is specified,it returns the address of the named device. When name is not specified, itreturns the primary ethernet device.Returns a list of the ethernet device names actually present on the system.This is a subset of the list returned by flag= 2. Listed names are separated bythe $CHAR(1) character.Returns the current list of ethernet device names, as set by Caché startup orby a subsequent invocation of $ZUTIL(114,2,name). Listed names areseparated by commas.nameEthernet device name(s). Valid values are:700 Caché ObjectScript Reference
$ZUTIL(114)When flag = 0When flag= 2name is the name of a specific ethernet device.$ZUTIL(114,0,name) returns the address of the named device.name is an ethernet device names list, enclosed in quotes withindividual device names separated by commas. A name listspecified in $ZUTIL(114,2) cannot contain control characters.ExamplesThe following example returns the address of the first ethernet adaptor found:SET Add=$ZUTIL(114,0)WRITE Addreturns 0000C0A5C222.The following example returns the address of a named ethernet adaptor:SET Add=$ZUTIL(114,0,"\\device\\NBf_SMCISA1")WRITE ADDreturns 0000C0A6C392.The following example returns a $CHAR(1) delimited list of ethernet adaptor names:SET R=$ZUTIL(114,1)FOR I=1:1:$LENGTH(R,$CHAR(1)) {WRITE $PIECE(R,$CHAR(1),I),!}returns:\\Device\\NwlnkNb\\Device\\Nbf_SMCISA1\\Device\\Nbf_NdisWan4The following example first returns a comma-delimited list of ethernet device names andthen replaces that list of names with the list of names specified:ZZDUMP $ZUTIL(114,2)returns: en0,en1,et0,et1WRITE !,$ZUTIL(114,2,"es0,es1"),"add one"WRITE !,$ZUTIL(114,1),"check one"WRITE !,$ZUTIL(114,2,"es2"),"add two"WRITE !,$ZUTIL(114,1),"check two"returns: en0,en1,et0,et1ZZDUMP $ZUTIL(114,2)Caché ObjectScript Reference 701
