How to export binary string from C to ruby?

[Guest]

Hi,

I'd like to write a ruby method in C, which passes an
arbitrary byte string as a result back to ruby.

All functions I found (like rb_str_new2 ) use
just a pointer and assume the string to be 0-terminated.

Any way to convert a buffer into a ruby string based
on pointer and length?

regards

I don't think rb_str_new() expects a null terminator:

VALUE rb_str_new _((const char*, long));
