[sane-devel] pthread support

Hi List,

Why is pthread disabled by default for Linux?

I'm just busy implementing SANE_STATUS_NO_DOCS for sane_read() in the
Pixma backend.

By default sane_start() forks a child process which handles the scan
procedure. So there is no chance for sane_read() to fetch the device
status without additional overhead for shared memory, pipes, etc.  With
enabled pthread sane_read() can fetch the device status.

Many thanks for your help in advance.
