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 NUL terminated string describing the block size, something like ``1K-blocks''. If the
headerlenp parameter is not NULL the memory referenced by headerlenp is filled in with the length of the string (not including the terminat-
ing NUL). If the blocksizep parameter is not 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.

Hi
Can someone please guide me on how to get the default block size for
all unix flavors.
As per my investigation its 512 for all unix flavours other than HP for which it is 1024.However I am not sure on this.
