Proof step 37 from proof inv-close (previous step)

of[fd] = mkfile(m, mode, m0), dom of < ino0, afs-cons(dirs, files), of-cons(of, dirs, files), fd ∈ of ⊦ ⟪fail#(; ; err); if err = ESUCCESS then {of := of -- fd; vfs_put_inode#(inode, of, asynced; err, dirs, files)}⟫ (of-cons(of, dirs, files) ∧ dom of < ino0 ∧ afs-cons(dirs, files))

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 38:
of[fd] = mkfile(m, mode, m0), dom of < ino0, afs-cons(dirs, files), of-cons(of, dirs, files), fd ∈ of ⊦ ⟪choose err0 with ⌊err0⌋ in err := err0; if err = ESUCCESS then {of := of -- fd; vfs_put_inode#(inode, of, asynced; err, dirs, files)}⟫ (of-cons(of, dirs, files) ∧ dom of < ino0 ∧ afs-cons(dirs, files))

Rule argument

pos: right 1

Additional information

Used simplifier rules: fail#(; ; ERR){choose ERR0 with ⌊ERR0⌋ in ERR := ERR0};
