GETBSIZE(3)		 BSD 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 de-
     scribing the block	size, something	like "1K-blocks".  The memory refer-
     enced by headerlenp is filled in with the length of the string (not in-
     cluding 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.
