Ok so then the following code: const char *op; pn_data_put_string(content, pn_bytes(strlen(op), op));
Gives me an error: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive] pn_data_put_string(content, pn_bytes(strlen(op), op)); If I use pn_bytes_dup instead, an error goes away, but I'm afraid this will result in memory leak. If put_string does not save the pn_bytes_t::start pointer internally but rather makes a copy I guess it should be safe to force the const_cast<char *> for pn_bytes_t::start?
