I wish to call some functions in a complex C library from D. Since this
a large & complex library, I've wrapped a bunch of the functions using
SWIG (swig -d -d2 ...). One of the C functions has a signature like:
void foo(const char * const *keys);
SWIG has given me a D function signature like:
void foo(char** keys);
In my D program it is natural to represent some keys as an array of
strings, for example:
string[] mykeys;
How should I convert mykeys from string[] to char** so that I can call
foo with mykeys as the actual parameter?
I think you need to do something like:
import std.conv;
string[] mykeys;
char*[] ckeys;
ckeys.reserve(mykeys.length);
foreach (key ; mykeys)
ckeys ~= to!(char*)(key);
foo(ckeys.ptr);
