-.Sh SYNOPSIS
-.In stdlib.h
-.Ft char *
-.Fn getbsize "int *headerlenp" "long *blocksizep"
-.Sh DESCRIPTION
-The
-.Fn getbsize
-function determines the user's preferred block size based on the value of the
-.Dq BLOCKSIZE
-environment variable; see
-.Xr environ 7
-for details on its use and format.
-.Pp
-The
-.Fn getbsize
-function returns a pointer to a null-terminated string describing
-the block size, something like
-.Dq 1K-blocks .
-The memory referenced by
-.Fa headerlenp
-is filled in with the length of the string (not including the
-terminating null).
-The memory referenced by
-.Fa blocksizep
-is filled in with block size, in bytes.
-.Pp
-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.
