LAM_RTRGET(2)		      LAM REMOTE LIBRARY		 LAM_RTRGET(2)

NAME
       lam_rtrget,  lam_rtrforget,  lam_rtrfget,  lam_rtrfforget  - Unload LAM
       trace data.

SYNOPSIS
       int lam_rtrget (int nodeid, int listno, int pid, char **buffer);

       int lam_rtrforget (int nodeid, int listno, int pid, char **buffer);

       int lam_rtrfget (int nodeid, int listno, int pid, int fd);

       int lam_rtrfforget (int nodeid, int listno, int pid, int fd);

DESCRIPTION
       The client function, lam_rtrget(), gets a copy of selected  trace  data
       held  by a remote trace daemon and stores it in space allocated and as‐
       signed to the buffer argument.  It does not  obtain  trace  data	 still
       stored  with  traced  processes	and not found in the daemon.  A traced
       process can be forced to flush its trace data by sending it a  SIGTRACE
       signal.	See MPIL_Signal(2).

       Trace  data  is	unloaded from the selected node and list (see lam_rtr‐
       store(2)) that was produced by the selected process ID.	A value of  -1
       for  listno  and/or  pid	 selects  all lists and/or all trace producing
       clients, respectively.  The combination effectively unloads all	stored
       trace data from the given node.

       Trace  data is read non-destructively by lam_rtrget() and destructively
       by lam_rtrforget().  The trace data is stored in	 an  allocated	buffer
       whose address is passed back to the caller through the buffer argument.
       The caller is responsible for calling free(3) on this pointer.

       Trace data is read into a file, instead	of  an	allocated  buffer,  by
       lam_rtrfget() and lam_rtrfforget().  The file is given as a descriptor,
       returned by open(2) and opened for write.
