strlcat(char *restrict, const char *restrict, size_t); size_t strlcpy(char

On page 494 line 17097-17146 section 2.4.3, add strlcat(), strlcpy(),
wcslcat(), and wcslcpy() to the table of async-signal-safe functions.
On page 2053 insert a new strlcat page:
NAMEstrlcat, strlcpy -- size-bounded string
concatenation and copying
SYNOPSIS#include
[CX]size_t strlcat(char *restrict dst, const char *restrict src,
size_t dstsize);
size_t strlcpy(char *restrict dst, const char *restrict src,
size_t dstsize);[/CX]
DESCRIPTIONThe strlcpy() and strlcat()
functions copy and concatenate strings, stopping when either a NUL
terminator in the source string is encountered or the specified full size
of the destination buffer is reached. They NUL terminate the result if
there is room. The application should ensure that room for the NUL
terminator is included in dstsize.
The strlcpy() function shall copy not more than dstsize - 1
bytes from the string pointed to by src to the array pointed to by
dst; a NUL byte in src and bytes that follow it shall not be
copied. A terminating NUL byte shall be appended to the result, unless
dstsize is 0. If copying takes place between objects that overlap,
the behavior is undefined.
The strlcat() function shall append not more than dstsize -
strlen(dst) - 1 bytes from the string pointed to by src to
the end of the string pointed to by dst; a NUL byte in src
and bytes that follow it shall not be appended. The initial byte of
src shall overwrite the NUL byte at the end of dst. A
terminating NUL byte shall be appended to the result, unless its location
would be at or beyond dst + dstsize. If copying takes place
between objects that overlap, the behavior is undefined.
The strlcpy() and strlcat() functions shall not change the
setting of errno on valid input.
RETURN VALUEUpon successful completion, the
strlcpy() function shall return the length of the string pointed to
by src; that is, the number of bytes in the string, not including
the terminating NUL byte.
Upon successful completion, the strlcat() function shall return the
initial length of the string pointed to by dst plus the length of
the string pointed to by src.
No return values are reserved to indicate an error.
ERRORSNo errors are defined.
EXAMPLESThe following example detects truncation while
combining a path prefix (including trailing ) and a filename to
produce a portable pathname:char *prefix, *filenam,
pathnam[_POSIX_PATH_MAX];
if (strlcpy(pathnam, prefix, sizeof pathnam) >= sizeof pathnam ||
strlcat(pathnam, filenam, sizeof pathnam) >= sizeof pathnam)
{
// truncation occurred
...
}
This code ensures there is room for the NUL terminator by:Calling
strlcpy() with a non-zero dstsize argument.
Only calling strlcat() if the return value of strlcpy()
indicated that truncation did not occur.
APPLICATION USAGEThe return value of the
strlcpy() and strlcat() functions follows the same convention
as snprintf(); that is, they return
