box.session.euid()

box.session.euid()¶

Return:	the effective user ID of the current user.

This is the same as box.session.uid(), except in two cases:

• The first case: if the call to box.session.euid() is within a function invoked by box.session.su(user-name, function-to-execute) – in that case, box.session.euid() returns the ID of the changed user (the user who is specified by the user-name parameter of the su function) but box.session.uid() returns the ID of the original user (the user who is calling the su function).
• The second case: if the call to box.session.euid() is within a function specified with box.schema.func.create(function-name, {setuid= true}) and the binary protocol is in use – in that case, box.session.euid() returns the ID of the user who created “function-name” but box.session.uid() returns the ID of the the user who is calling “function-name”.
