This procedure is defined in the server but not documented via ad_proc or proc_doc and may be intended as a private interface.
The procedure is defined as:

set path [dict get $file path]
file stat $path st
set f [open $path rb]
try {
set prefix [read $f [string length [dict get $file prefix]]]
} finally {
close $f
}
# Appends to the active log are outside the fixed snapshot and permitted.
