/* 
 * Modification History : DO NOT EDIT - MAINTAINED BY CVS 
 * $Log: keyValuePair.h,v $
 * Revision 1.1  2004/08/31 15:48:09  rjn
 * Um... lots of additions. The biggest ones are switching from shared to static libraries, and the additon of configLib and kvpLib to read formatted config files. These two libraries were created by Gordon Crone (gjc@hep.ucl.ac.uk) and are in spirit released under the GPL license.
 * Also the first of the actually programs (Eventd) has been started. At the moment it just opens a socket to fakeAcqd. Other sockets and better handling of multiple sockets in socketLib are the next things on my to do list.
 *
 * Revision 1.11  2004/03/04 16:15:56  gjc
 * Grow internal buffer (by allocating larger buffer and copying data) as
 * necessary.
 *
 * Revision 1.10  2004/03/04 11:50:20  gjc
 * Added new function kvpQueryLength to return the number of elements in
 * an array.
 *
 * Revision 1.9  2004/01/23 17:40:24  gjc
 * double size of buffer (KVP_BUFFER_SIZE).
 *
 * Revision 1.8  2003/09/04 21:06:16  gjc
 * Use malloc instead of static array.  Move BUFFER_SIZE in keyValuePair.c to KVP_BUFFER_SIZE in keyValuePair.h
 *
 * Revision 1.7  2003/07/31 16:53:01  gjc
 * Invalidate old key and skip it from kvpFormat when overwriting in kvpParse
 *
 * Revision 1.6  2003/02/27 12:34:36  gjc
 * Robert Hatcher's mods to avoid warnings with gcc 3.2
 *
 * Revision 1.1  2003/02/25 21:18:40  rhatcher
 * key-value pair string en/decoding that the DAQ group uses.  Comes through
 * in the RawRunConfigBlock (which holds the "run prepare" string).
 * small modifications to "official" version to eliminate warning messages.
 *
 * Revision 1.5  2003/02/13 15:41:18  gjc
 * Increased MAXKEYS and check for exceding it in kvpParse
 *
 * Revision 1.4  2001/07/24 17:19:55  gjc
 * Added new function kvpGetStringArray
 *
 * Revision 1.3  2001/05/16 11:52:09  gjc
 * Added new function kvpUpdateInt needed for run number kludge.
 * Removed reference to syslog and added new error code KVP_E_TERMINATOR
 * for missing semi-colon.
 *
 * Revision 1.2  2001/04/11 16:27:05  gjc
 * Stricter checking of numeric values in kvpParse.  Fixes bug with
 * inconsistent element count for hex values.
 * No longer start again at beginnning of internal buffers every time
 * kvpParse is a called.  Must call kvpReset before kvpParse if that's
 * what you want.
 *
 * Revision 1.1  2001/03/26 18:09:21  gjc
 * initial check in
 *
