NAME

       XPAName -  What does XPA stand for?

SYNOPSIS

       What does XPA stand for? Who knows anymore!

DESCRIPTION

       What does XPA stand for? Dunno! The XPA messaging system originally was built on top of the X Window System and XPA was the mnemonic for X
       Public Access, to emphasize that we were providing public access to previously private data and algorithms in Xt programs.  Now that XPA no
       longer is tied to X, it can be argued that we ought to change the name (how about SPAM: simple public access mechanism ), but XPA is in
       wide-spread use in the astronomical community of its birth, and the name has taken on a life of its own. If anyone can think of what XPA
       now means, please let us know.

       If you think this is bad, consider the MMT Telescope on Mount Hopkins, Arizona. When first installed twenty years ago, it featured an array
       of six 72-inch diameter mirrors. from which came its name: the Multiple Mirror Telescope.  In spring of 1999, these mirrors were replaced
       by a single 21 and 1/2 -foot diameter primary mirror, the largest single-piece glass reflector on the North American continent. And now
       MMT stands for ... MMT!

NAME

       XPACmdAdd -  add a command to an XPA command public access point

SYNOPSIS

	 #include <xpa.h>

	 XPACmd XPACmdAdd(XPA xpa, char *name, char *help,
			  int (*send_callback)(),
			  void *send_data, char *send_mode,
			  int (*rec_callback)(),
			  void *rec_data,  char *rec_mode);

DESCRIPTION

       Add a command to an XPA command access point. The XPA argument specifies the XPA struct returned by a call to XPANewCmd(). The name argu-
       ment is the name of the command. The other arguments function identically to the arguments in the XPANew() command, i.e., the send_callback
       and rec_callback routines have identical calling sequences to their XPANew() counterparts, with the exceptions noted below.

       When help is requested for a command access point using:

	 xpaget -h class:name

       all of the command help strings are listed.  To get help for a given command, use:

	 xpaget -h class:name cmd

       Also, the acl keyword in the send_mode and receive_mode strings is global to the access point, not local to the command.  Thus, the value
       for the acl mode should be the same in all send_mode (or receive_mode) strings for each command in a command access point. (The acl for
       send_mode need not be the same as the acl for receive_mode, though).
