Solaris <sys/errno.h> has: #define EWOULDBLOCK EAGAIN so checking (errno == EAGAIN || errno == EWOULDBLOCK) is overkill. This leads cppcheck 1.62 to complain: [xserver/os/io.c:365] -> [xserver/os/io.c:365]: (style) Same expression on both sides of '||'. [xserver/os/io.c:941] -> [xserver/os/io.c:941]: (style) Same expression on both sides of '||'. This quiets it, and reduces the number of calls Solaris Studio cc generates to the __errno() function to get the thread-specific errno value.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
