BLISTRFRG()
------------------------------------------------------------------------------
Purpose:
Get CA-Clipper Summer '87 free pool fragmentation as a string.
Syntax:
cValue = BLISTRFRG([cString])
Parameters:
cString String containing block characters.
Returns:
Fragmentation as a string.
Description:
This function returns a string containing a summary of CA-Clipper Summer
'87's dynamic memory to show the degree of fragmentation. Each character
position represents up to 512 bytes, and adjacent equal characters
represent contiguous blocks larger than 512 bytes.
The optional parameter is a five character string in the form "ffuua" as
described below. The first two characters (ff) are used to represent free
blocks and the next two characters (uu) to represent used blocks, with the
final character (a) used to represent the next allocation point. The
returned string contains a map of both the near heap and the far heap (FREE
POOL), separated by a ',' character. The layout and meaning of the display
is detailed in the discussion of the function BLIDISFRG().
Example:
// Get the string showing memory fragmentation
// Use 'f' for all free blocks, 'u' for all used
//
TMPSTRFRG = BLISTRFRG("ffuua")
? "The state of dynamic memory is currently"
? TMPSTRFRG
