I would strongly lean towards std::string if possible.
I'm not sure how a realloc on the heap is any less safe than a std::string
and strings can have memory reserved at construction time (or
::reserve()). Or in crazy cases, a custom allocator can be used that has a
preallocated pool of memory

Well, I don't think the hack is really needed and char szLastErrorMsg[] could
be
replaces by a char* pszLastErrorMsg
I now know this is referred to as the "struct hack."
This really is undefined behavior in the C++11 standard... there was a
proposal to make the struct hack valid for C++11:

Not a big deal but I was trying to open a JP2 file using the MrSID driver

Well, this is a good old trick of grey-beard C programmers, isn't it ? Not sure
what the C/C++ standards says about that,

I'm just trying to load the census roads data. I think what happened is
that when the table was created using -nlt PROMOTE_TO_MULTI it was
created as polygon geometry. then the subsequent insert failed. I change
the script to -nlt MULTILINESTRING and it loaded all the data. I found a
post from
You could use -nlt geometry but that won't convert simple objects to multi
objects.
You could do it in steps:
1. use -where to get lines and -nlt MultiLine
2. use -where to get polys with -nlt MutliPolygon
3. combine the two tables into a single Geometry table

Hi,
another, may be simpler option is SAGA GIS, its analytical hillshading
tool includes a ray tracing option:

Dear GDAL people:
Using DSM, I want a "shadow map" not only by the slope
itself but also by the other slopes. I mean, if a tall and
steep peak exists, and if it is illuminated by the sun from
near the horizon, the shadow of the peak falls on a wide
area of the foot of the mountain. Such shadow
