Hi all,
I don't know if it is the best place to ask this question, but I'll try it. I
am trying to wrap around a following function:
OGRErr OSRExportToProj4(OGRSpatialReferenceH r, char **buff);
This function allocates the string and assigns it to the (char*) pointer passed
as buff and then its contents should be copied into a C string and the obtained
pointer released via CPLFree();
So, basically, in C a typical usage would be:
char *proj = NULL:
OSRExportToProj4(handle, &proj);
printf("%s\n", proj);
CPLFree(proj);
And the question is: how is this function should be wrapped with CFFI?
Thanks,
Victor
