GETBSIZE(3)	       FreeBSD Library Functions Manual		   GETBSIZE(3)

NAME
     getbsize -- get user block	size

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     char *
     getbsize(int *headerlenp, long *blocksizep);

DESCRIPTION
     The getbsize() function determines	the user's preferred block size	based
     on	the value of the ``BLOCKSIZE'' environment variable; see environ(7)
     for details on its	use and	format.

     The getbsize() function returns a pointer to a null-terminated string
     describing	the block size,	something like ``1K-blocks''.  The memory ref-
     erenced by	headerlenp is filled in	with the length	of the string (not
     including the terminating null).  The memory referenced by	blocksizep is
     filled in with block size,	in bytes.

     If	the user's block size is unreasonable, a warning message is written to
     standard error and	the returned information reflects a block size of 512
     bytes.

SEE ALSO
     df(1), du(1), ls(1), systat(1), environ(7)

HISTORY
     The getbsize() function first appeared in 4.4BSD.
