MPE_Describe_comm_state(4)	      MPE	    MPE_Describe_comm_state(4)

NAME
       MPE_Describe_comm_state	-   Describe  attributes  of a state with byte
       informational data in a specified MPI_Comm and on the thread  that  the
       function is invoked.

SYNOPSIS
       int MPE_Describe_comm_state( MPI_Comm comm,
				    int state_startID, int state_finalID,
				    const char *name, const char *color,
				    const char *format )

INPUT PARAMETERS
       comm   - MPI_Comm where this process is part of.
       state_startID
	      - event number for the starting of the state.
       state_finalID
	      - event number for the ending of the state.
       name   -	 name  of the state, the maximum length of the NULL-terminated
	      string is, sizeof(CLOG_DESC), 32.
       color  - color of the state, the maximum length of the  NULL-terminated
	      string is, sizeof(CLOG_COLOR), 24.
       format -	 printf style %-token format control string for the state, the
	      maximum	length	 of    the    NULL-terminated	 string	   is,
	      sizeof(CLOG_FORMAT), 40.	If format is NULL, it is equivalent to
	      calling MPE_Describe_state().  The  fortran  interface  of  this
	      routine  considers  the zero-length string, "", and single-blank
	      string, " ", as NULL.

NOTES
       Adds a state definition to the logfile.	States are added to a  logfile
       by calling 'MPE_Log_comm_event()' for the start and end event numbers.

       This function is threadsafe.

NOTES ON STORAGE FORMAT CONTROL SUPPORT
       The format control string is printf like, e.g. "Comment = %s".  All the
       MPE %-token storage support is provided by SLOG-2.   That  is  whatever
       supported by SLOG-2 will be supported by MPE.  Currently, the following
       is supported.

       %s : variable length string, byte buffer size is length of string + 2.

       %h : 2-byte integer, printed as decimal integer, byte buffer size is 2.

       %d : 4-byte integer, printed as decimal integer, byte buffer size is 4.

       %l : 8-byte integer, printed as decimal integer, byte buffer size is 8.

       %x : 4-byte integer, printed as hexadecimal integer, byte  buffer  size
       is 4.

       %X  :  8-byte integer, printed as hexadecimal integer, byte buffer size
       is 8.

       %e : 4-byte float, printed as decimal float, byte buffer size is 4.

       %E : 8-byte float, printed as decimal float, byte buffer size is 8.
