MPE_Log_pack(4)			      MPE		       MPE_Log_pack(4)

NAME
       MPE_Log_pack  -	pack the informational data into the byte buffer to be
       stored in a infomational	event.	The routine will byteswap the data  if
       it is invoked on	a small	endian machine.

SYNOPSIS
       int MPE_Log_pack( MPE_LOG_BYTES bytebuf,	int *position,
			 char tokentype, int count, const void *data )

OUTPUT PARAMETERS
       bytebuf
	      -	 output	byte buffer which is of	sizeof(MPE_LOG_BYTES), i.e. 32
	      bytes.  For C, bytebuf could be of type MPE_LOG_BYTES.  For For-
	      tran, bytebuf could be of	type 'character*32'.
       position
	      -	 an offset measured from the beginning of the bytebuf.	On in-
	      put, data	will be	written	to the offset  position.   On  Output,
	      position	will be	updated	to reflect the next available position
	      in the byte buffer.

INPUT PARAMETERS
       tokentype
	      -	a character token type indicator, currently  supported	tokens
	      are 's', 'h', 'd', 'l', 'x', 'X',	'e' and	'E'.
       count  -	 the number of continuous storage units	as indicated by	token-
	      type.
       data   -	pointer	to the beginning of the	storage	units being copied.

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.
