getbsize
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.
