getlogin()               General Function              getlogin()




Get login name

cchhaarr *ggeettllooggiinn()

The name  corresponding to the current user id  is not always the
same as the name under which a user logged into the COHERENT sys-
tem.   For example,  the user  may have issued  a su  command, or
there may be several login names associated with a user id.  get-
login returns the login name found in the file /etc/utmp.

In  cases where  getlogin  fails to  produce  a result,  getpwuid
(described in  getpwent) is normally  used to determine  the user
name for a process.
