Subject: [PATCH] Rewind utmp file pointer after searching for entry
|
|
|
|
getutline() advances the file pointer until it matches or reaches EOF. pututline() starts from the current position in utmp. This rewinds the file pointer to the beginning to avoid allocating additional spurious utmp entries.
