Signature

(gnus-atomic-progn &rest FORMS)

Documentation

Evaluate FORMS atomically, which means to protect the evaluation from being interrupted by the user. An error from the forms themselves will return without finishing the operation. Since interrupts from the user are disabled, it is recommended that only the most minimal operations are performed by FORMS. If you wish to assign many complicated values atomically, compute the results into temporary variables and then do only the assignment atomically.
