Daniel Stenberg	3df42ca949	dynbuf: return NULL when there's no buffer length ... ... as returning a "" is not a good idea as the string is supposed to be allocated and returning a const string will cause issues. Reported-by: Brian Carpenter Follow-up to ed35d6590e Closes #5405	2020-05-17 23:20:56 +02:00
Daniel Stenberg	18815aa670	ngtcp2: convert to dynbuf ... Closes #5335	2020-05-04 14:57:57 +02:00
Daniel Stenberg	ed35d6590e	dynbuf: introduce internal generic dynamic buffer functions ... A common set of functions instead of many separate implementations for creating buffers that can grow when appending data to them. Existing functionality has been ported over. In my early basic testing, the total number of allocations seem at roughly the same amount as before, possibly a few less. See docs/DYNBUF.md for a description of the API.
