[Plplot-devel] [PATCH] plAllooc2dGrid/plFree2dGrid

[David M. <da...@as...>]

Humbly offered for your consideration...

After the attached patch (plus the other attached "uncrustify"  
patch),  plAlloc2dGrid will allocate one block of memory that is big  
enough for nx pointers plus nx*ny PLFLTs.  This means only one call  
to malloc and only one call to free no matter how big nx is.  It also  
avoids the "bug" in plAlloc2dGrid that neglects to free memory  
already allocated if fewer than nx of the ny-element arrays can be  
allocated.

I have tested this patch using x08c and x011c (both of which use  
these functions considerably).  The examples work and no leaks were  
introduced (according to the "leaks" command).
