getbsize -- get user block size
Standard C Library (libc, -lc)
#include <stdlib.h>
char *
getbsize(int *headerlenp, long *blocksizep);
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 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.
