 * $Log: utilitaires.h,v $
 * Revision 1.11  2008/08/19 06:41:59  j_novak
 * Minor modifications to avoid warnings with gcc 4.3. Most of them concern
 * cast-type operations, and constant strings that must be defined as const char*
 *
 * Revision 1.10  2004/09/01 09:47:55  r_prix
 * fixed/improved string-reading with read_variable(): allocates returned string
 *
 * Revision 1.9  2004/03/22 13:12:44  j_novak
 * Modification of comments to use doxygen instead of doc++
 *
 * Revision 1.8  2003/12/17 23:12:30  r_prix
 * replaced use of C++ <string> by standard ANSI char* to be backwards compatible
 * with broken compilers like MIPSpro Compiler 7.2 on SGI Origin200. ;-)
 *
 * Revision 1.7  2003/12/05 15:05:53  r_prix
 * added read_variable() for (C++-type) strings.
 *
 * Revision 1.6  2003/12/04 12:33:21  r_prix
 * added prototypes and documentation for variable-reading functions
 * (read_variable, load_file, load_file_buffered)
 *
 * Revision 1.5  2002/05/02 15:16:22  j_novak
 * Added functions for more general bi-fluid EOS
 *
 * Revision 1.4  2002/04/16 08:06:44  j_novak
 * Addition of zerosec_borne
 *
 * Revision 1.3  2002/04/11 09:19:46  j_novak
 * Back to old version of zerosec
 *
 * Revision 1.2  2001/12/04 21:24:33  e_gourgoulhon
 *
 * New functions fwrite_be and fread_be for writing/reading in a
 * binary file according to the big endian convention.
 *
 * Revision 1.1.1.1  2001/11/20 15:19:27  e_gourgoulhon
 * LORENE
 *
 * Revision 1.6  2001/09/14  14:23:53  eric
 * Ajout de la fonction zero_list.
 *
 * Revision 1.5  2001/05/29  16:11:21  eric
 * Modif commentaires (mise en conformite Doc++ 3.4.7).
 *
 * Revision 1.4  1999/12/24  12:59:54  eric
 * Ajout de la routine zero_premier.
 *
 * Revision 1.3  1999/12/15  15:39:42  eric
 * *** empty log message ***
 *
 * Revision 1.2  1999/12/15  15:17:03  eric
