NAME

getbsize- get user block size

SYNOPSIS

#include <stdlib.h>

char *getbsize(int *headerlenp, long *blocksizep);

API RESTRICTIONS

The function or functions documented here may not be used safely in all application contexts with all APIs provided in the ChorusOS 5.0 product.

See API(5FEA) for details.

DESCRIPTION

The getbsize() function determines the user's preferred block size based on the value of the BLOCKSIZE environment variable (see environ(4)).

This 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.
