It can also mean a preallocated array of strings, though; C is sloppy about
In that case it's a pointer to a pointer: since in C a function can't
multiple values, when one wants to return two strings, one needs to use
several char ** arguments in the function call.
The caller passes a reference to a pointer and the function returns the
address of a malloc-ed memory area wi
A C char** is an array (of unknown length) of pounters to C strings ( each of
unknown length).
I don't know NativeCall, can't tell you how it should be declared, but I hope
that highlights the issue.
Hello,
Please excuse my naivety, I'm trying to use NativeCall to interface a Perl6
program with a C library and I have a problem mapping a char ** argument.
The C function has this prototype:
void function(char **arg1, char **arg2);
I read that declaring a sub with Str rw parameters would do th
