KENTER(2) LAM LOCAL LIBRARY KENTER(2) NAME kenter - Enter process into LAM session. C SYNOPSIS int kenter (char *name, int priority); FORTRAN SYNOPSIS subroutine KENTR (name, priority, ierr) character name*(*) integer priority, ierr DESCRIPTION kenter() is the first function a LAM process must call to subsequently use LAM services. By calling underlying functions, kenter() accom- plishes three important tasks. It initializes all relevant LAM data structures, particularly those for communication with the LAM daemon (see kinit(2)). It registers with the local LAM daemon and sets the message synchronizing priority (see kattach(2)). It also establishes a readable name by which the process can be remotely monitored and con- trolled (see lpattach(2)). The name argument should be the name of the program (argv[0] is recom- mended) and becomes a convenient recognition string(3,n) in(1,8) the output of the state(1) command. It is not used for any type of synchronization. Process Scheduling LAM processes are scheduled by the host(1,5) operating system. The priority argument determines which process will be synchronized first when many are blocked on the same message event and type (see ksend(2)). The highest priority process is always favoured. The LAM daemon works like a server. By not replying to a message pass- ing request, it can effectively block a process from running. The dae- mon will also attempt to preempt a running process when delivering a LAM signal(2,7) (see kdoom(2)). ERRORS ENOKERNEL LAM is not running on the local node. ENOKDESCRIPTORS The LAM daemon ran out of process descriptors. SEE ALSO kinit(2), kattach(2), lpattach(2) LAM 7.0.6 May, 2004 KENTER(2)
