[libmicrohttpd] MHD_create_response_from_fd using a pipe

[Denis Dowling]

Hi,

 

I am looking at generating some content from the result of a zip process and it would be neat if I could get the popen() pipe to push data directly into MHD_create_response. It looks like this would almost work by using MHD_create_response_from_callback but also setting the response->fd to be the fd of the pipe returned by popen(). Read callback would be mostly the same as happens for a file. The size would be set to -1 for chunked output. pclose() call could be run from the free callback.

 

Has anyone done something like this before? There is an issue that the response->fd is opaque from user code and would need some function to expose.

 

Regards,

Denis
