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 describing the block size, some-thing something
thing like ``1K-blocks''. The memory referenced 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.
