As such, they are most often found as members 13of Mesh Arrays. While it is possible to use Path Arrays 14directly to define 1-dimensional regular connections, they will not be recognized 15through the usual #!F-adobe-times-bold-r-normal--18* DXQueryGridConnections #!EF interface, and, in some cases, 16will not be handled without expansion. It is therefore preferable to 17use #!F-adobe-times-bold-r-normal--18* DXMakeGridConnections #!EF and #!F-adobe-times-bold-r-normal--18* DXQueryGridConnections #!EF to define and 18access 1-dimensional regular grids. #!N #!N Array handles offer a simple 19mechanism to access individual elements of a Path Array without expansion. 20#!N #!N Return Value #!N #!N Returns #!F-adobe-times-bold-r-normal--18* a #!EF or 21returns #!F-adobe-times-bold-r-normal--18* NULL #!EF and sets an error code. #!N #!N 22See Also #!N #!N #!F-adobe-times-bold-r-normal--18* #!Ldxcah,dxall1189 h DXCreateArrayHandle #!EL , #!Ldxgpo,dxall1259 h DXGetPathOffset #!EL , #!Ldxmgcv,dxall1297 h DXMakeGridConnections, DXMakeGridConnectionsV #!EL , 23 #!Ldxnpa,dxall1321 h DXNewPathArray #!EL , #!Ldxqgc,dxall1343 h DXQueryGridConnections #!EL , #!Ldxspo,dxall1386 h DXSetPathOffset #!EL #!EF #!N #!N #!Lphas,dxall1076 h Path Arrays #!EL . #!N 24#!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ldxgpo,dxall1259 h DXGetPathOffset #!EL #!N #!F-adobe-times-medium-i-normal--18* 25#!N 26
