the recent commits converted the tabs to 4 spaces, which matched the
initial indent size. Other commits converted the tabs to 8 spaces, this
didn't match.
All the code has been converted to 4 space indents. No changes to line
lengths or actual code was performed. This is in preperation to my up
coming non-blocking work so my commits should only be code changes and
line lengths in the code I am working on.
* The following low level packet routines now fully support non-blocking:
libssh2_sftp_packet_read()
libssh2_sftp_packet_ask()
libssh2_sftp_packet_require()
libssh2_sftp_packet_requirev()
* libssh2_sftp_readdirnb() functions completely in non-blocking mode
* The rest of the routines which call the libssh2_sftp_packet_* routine
loop on a return code of PACKET_EAGAIN. This maintains the current
functionality until they fully support non-blocking
* The state of all function are labeled with either NB-SAFE or NB-UNSAFE,
for those that are know. NB-UNSAFE?? for those that haven't been
examined.
blocking way. The channel code is now responsible for enabling/disabling
blocking status and to work with it.
I've also modified indenting and fixed compiler warnings at places, and
added a bunch of new examples in example/simple that I've used to verify that
the code still runs like before.
libssh2_channel_{read|write}nb_ex() and libssh2_sftp_{read|write}nb() are the
four new functions that supposedly work non-blocking.
The convience functions pass in the return from strlen() which is "size_t",
usually an "unsigned long". This created the possiblility of passing in
a value that could look negative.
All "int" lengths were converted to "unsigned int". Ideally they should
all become "size_t", but that is a bigger change. This is a good start.
