[GRASS-dev] Documentation about Directed Graph Library (DGLib)

rabotin · August 5, 2010, 2:24pm

Dear all,
i'm developing some c scripts for GRASS 6.4 under ubuntu system. One of my script needs to "travel" on N-ary tree (which represents hydrological networks). So I wanted to use the DGLib library for my graph but there is so few documentation about the different dgl_* functions that I have lots of difficulties to use it. Does anybody have some more complete documentation about this library ?
Thanks in advance for any response !

Thanks for the fast answer but for lots of dglib functions (like dglGetEdge) there is no documentation . Do you if it's possible to have additional documentation. I've searched for grass add on scripts which can use dglib library (or work with graph concepts) to have some tips from these scripts but i found only v.strahler and it seems that this code doesn't use the dglib library.
