+ * literal containing a conversion specifier, possibly modified by
+ * a prefix such as hh, h, l, or ll, suitable for use within the
+ * format argument of a formatted input/output function when
+ * converting the corresponding integer type.  These macro names
+ * have the general form of PRI (character string literals for the
+ * fprintf family) or SCN (character string literals for the fscanf
+ * family), followed by the conversion specifier, followed by a
+ * name corresponding to a similar typedef name.  For example,
+ * PRIdFAST32 can be used in a format string to print the value of
+ * an integer of type int_fast32_t.

+ * Protocol for the local binder service, or pmap.
+ *
+ * The following procedures are supported by the protocol:
+ *
+ * PMAPPROC_NULL() returns ()
+ * 	takes nothing, returns nothing
+ *
+ * PMAPPROC_SET(struct pmap) returns (bool_t)
+ * 	TRUE is success, FALSE is failure.  Registers the tuple
+ *	[prog, vers, prot, port].
+ *
+ * PMAPPROC_UNSET(struct pmap) returns (bool_t)
+ *	TRUE is success, FALSE is failure.  Un-registers pair
+ *	[prog, vers].  prot and port are ignored.
+ *
+ * PMAPPROC_GETPORT(struct pmap) returns (unsigned long).
+ *	0 is failure.  Otherwise returns the port number where the pair
+ *	[prog, vers] is registered.  It may lie!
+ *
+ * PMAPPROC_DUMP() RETURNS (struct pmaplist *)
+ *
+ * PMAPPROC_CALLIT(unsigned int, unsigned int, unsigned int, string<>)
+ * 	RETURNS (port, string<>);
+ * usage: encapsulatedresults = PMAPPROC_CALLIT(prog, vers, proc, encapsulatedargs);
+ * 	Calls the procedure on the local machine.  If it is not registered,
+ *	this procedure is quite; ie it does not return error information!!!
+ *	This procedure only is supported on rpc/udp and calls via
+ *	rpc/udp.  This routine only passes null authentication parameters.
+ *	This file has no interface to xdr routines for PMAPPROC_CALLIT.
+ *
+ * The service supports remote procedure calls on udp/ip or tcp/ip socket 111.

+ *  SYSEXITS.H -- Exit status codes for system programs.
+ *
+ *	This include file attempts to categorize possible error
+ *	exit statuses for system programs, notably delivermail
+ *	and the Berkeley network.
+ *
+ *	Error numbers begin at EX__BASE to reduce the possibility of
+ *	clashing with other exit statuses that random programs may
+ *	already return.  The meaning of the codes is approximately
+ *	as follows:
+ *
+ *	EX_USAGE -- The command was used incorrectly, e.g., with
+ *		the wrong number of arguments, a bad flag, a bad
+ *		syntax in a parameter, or whatever.
+ *	EX_DATAERR -- The input data was incorrect in some way.
+ *		This should only be used for user's data & not
+ *		system files.
+ *	EX_NOINPUT -- An input file (not a system file) did not
+ *		exist or was not readable.  This could also include
+ *		errors like "No message" to a mailer (if it cared
+ *		to catch it).
+ *	EX_NOUSER -- The user specified did not exist.  This might
+ *		be used for mail addresses or remote logins.
+ *	EX_NOHOST -- The host specified did not exist.  This is used
+ *		in mail addresses or network requests.
+ *	EX_UNAVAILABLE -- A service is unavailable.  This can occur
+ *		if a support program or file does not exist.  This
+ *		can also be used as a catchall message when something
+ *		you wanted to do doesn't work, but you don't know
+ *		why.
+ *	EX_SOFTWARE -- An internal software error has been detected.
+ *		This should be limited to non-operating system related
+ *		errors as possible.
+ *	EX_OSERR -- An operating system error has been detected.
+ *		This is intended to be used for such things as "cannot
+ *		fork", "cannot create pipe", or the like.  It includes
+ *		things like getuid returning a user that does not
+ *		exist in the passwd file.
+ *	EX_OSFILE -- Some system file (e.g., /etc/passwd, /var/run/utmp,
+ *		etc.) does not exist, cannot be opened, or has some
+ *		sort of error (e.g., syntax error).
+ *	EX_CANTCREAT -- A (user specified) output file cannot be
+ *		created.
+ *	EX_IOERR -- An error occurred while doing I/O on some file.
+ *	EX_TEMPFAIL -- temporary failure, indicating something that
+ *		is not really an error.  In sendmail, this means
+ *		that a mailer (e.g.) could not create a connection,
+ *		and the request should be reattempted later.
+ *	EX_PROTOCOL -- the remote system returned something that
+ *		was "not possible" during a protocol exchange.
+ *	EX_NOPERM -- You did not have sufficient permission to
+ *		perform the operation.  This is not intended for
+ *		file system problems, which should use EX_NOINPUT or
+ *		EX_CANTCREAT, but rather for higher level permissions.
+ *	EX_CONFIG -- Something was found in an unconfigured or
+ *		misconfigured state.

+ *		Allocates a combined TIB and pthread memory region.
+ *		The argument is the amount of space to reserve
+ *		for the pthread structure.  Returns a pointer to
+ *		the TIB inside the allocated block.
+ *
+ * 	_dl_free_tib(tib, sizeof(struct pthread))
