Hello,
I believe that the following man page contains an error: <www dot unix dot com>/man-page/posix/1posix/eval/
In section "EXAMPLES", the fourth line should probably be:
eval y='$'$x
rather than:
$fooeval y='$'$x

fetch
FETCH(9) BSD Kernel Developer's Manual FETCH(9)NAME
fetch, fubyte, fuibyte, fusword, fuswintr, fuword, fuiword -- fetch data from user-space
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
int
fubyte(const void *base);
int
fusword(const void *base);
int
fuswintr(const void *base);
long
fuword(const void *base);
DESCRIPTION
The fetch functions are designed to copy small amounts of data from user-space.
The fetch routines provide the following functionality:
fubyte() Fetches a byte of data from the user-space address base.
fusword() Fetches a short word of data from the user-space address base.
fuswintr() Fetches a short word of data from the user-space address base. This function is safe to call during an interrupt context.
fuword() Fetches a word of data from the user-space address base.
RETURN VALUES
The fetch functions return the data fetched or -1 on failure. Note that these functions all do "unsigned" access, and therefore will never
sign extend byte or short values. This prevents ambiguity with the error return value for all functions except fuword().
SEE ALSO copy(9), store(9)BUGS
The function fuword() has no way to unambiguously signal an error, because the data it reads might legitimately be the same as the -1 used to
indicate an error. The other functions do not have this problem because the unsigned values returned by those can never match the -1 error
return value.
