CAPS_SYS_PUT(2)		    BSD System Calls Manual	       CAPS_SYS_PUT(2)

NAME
     caps_sys_put — send an opaque message to a CAPS IPC port

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/caps.h>

     off_t
     caps_sys_put(int portid, const void *msg, int msgsize);

DESCRIPTION
     Send an opaque message msg of the specified size msgsiz to the port iden‐
     tified by portid.	The memory associated with the message must be left
     intact until the message is returned.  The kernel does not make a copy of
     the message and its size may not exceed 128KB.

     This function is only used on the client side.

RETURN VALUES
     On success, this function returns a 64 bit message identifier.  If an
     error occurs, -1 is returned and errno is set.

ERRORS
     This function will fail if:

     [EINVAL]	 An invalid argument was specified.

     [ENOTCONN]	 The process originally creating the port forked and the child
		 process attempts to access the port.  The child process is
		 expected to create its own port.  This error is also returned
		 if the remote end closed its connection and is no longer
		 available.

     [ENOBUFS]	 The maximum number of in-transmit messages has been reached.
		 No more messages can be sent until some of them are replied
		 to.
