Why should this be done? POSIX [1] does not require this. Portable applications have to check against both EAGAIN and EWOULDBLOCK. > It was inspired by the flock patch. flock() is documented to use EWOULDBLOCK in some cases. The right action in this case IMO is to make the 'flock' module depend on the 'errno' module. Bruno [1] http://www.opengroup.org/susv3xbd/errno.h.html
