Top Forums Shell Programming and Scripting Extract sequences of bytes from binary for differents blocks Post 302850071 by Ophiuchus on Tuesday 3rd of September 2013 11:15:28 PM

Hello Chubler_XL,

I've added the fflush(stdout) after several printf lines within the code and now the program processes 373 more blocks.
Before the addition of flush it stopped in the block 581,524 and now, with the flush, stops in block 581,897.

It seems that is not related with the size of the blocks, more it seems that is accumulating memory or something and when
reaches the limit, stops.

Maybe you can see if something could be fixed to avoid this issue.

Thanks for all help so far.

fs_getcacheparms

FS_GETCACHEPARMS(1)					       AFS Command Reference					       FS_GETCACHEPARMS(1)

NAME

       fs_getcacheparms - Displays the current size and usage of the cache

SYNOPSIS

       fs getcacheparms [-help] [-files] [-excessive]

       fs getca [-h] [-files] [-excessive]

DESCRIPTION

       The fs getcacheparms command displays the current size of the cache (which can be in memory or on disk), and the amount currently in use.

       The reported statistics are from kernel memory, so the reported size can differ from the setting specified in the /etc/openafs/cacheinfo
       file on a machine using a disk cache, if the fs setcachesize command has been used to alter cache size.

OPTIONS

       -help
	   Prints the online help for this command. All other valid options are ignored.

       -files
	   Displays the current number of cache files in use, and the maximum available, as well as displaying the current cache size.

       -excessive
	   Displays detailed cache statistics, including the flags set on each cache element, and the distribution of cache entries by size.

OUTPUT

       The output reports

	  AFS using <amount> of the cache's available <size> 1K byte blocks.

       where <amount> is the number of kilobyte blocks currently used to cache data and status information, and <size> is the total current cache
       size.

EXAMPLES

       The following example shows the output on a machine with a 25000 kilobyte cache.

	  % fs getcacheparms
	  AFS using 22876 of the cache's available 25000 1K byte blocks.

       The following shows the output when asked to show file information.

	  % fs getcacheparm -files
	  AFS using	0% of cache blocks (897 of 200000 1k blocks)
			1% of the cache files (79 of 6250 files)

       And finally, the following detailed information can be obtained by using the excessive flag

	  % fs getcacheparm -excessive
	  AFS using	0% of cache blocks (897 of 200000 1k blocks)
			1% of the cache files (79 of 6250 files)
