They are listed in the X Protocol reference. There are various forms  
available online, such as freedesktop's xorg document repository.  
This will also tell you what the error code means in reference to the  
particular request.

The error codes are also listed in XCB's generated xproto.h  
(unqualified, unfortunately, because the docs also don't qualify them).

/** Opcode for xcb_value. */
#define XCB_VALUE 2
