/* wsp-strings.h: interface to tables defined by WSP standard
 *
 * This file defines an interface to the Assigned Numbers tables
 * in appendix A of the WSP specification.  For each supported
 * table there is a function to convert from number to string and
 * a function to convert from string to number.
 *
 * The tables are in wsp-strings.def, in a special format suitable for
 * use with the C preprocessor, which we abuse liberally to get the
 * interface we want. 
 *
 * For a table named foo, these functions will be declared:
 *
 * Octstr *wsp_foo_to_string(long number);
 *   - return NULL if the number has no assigned string.
 * 
 * unsigned char *wsp_foo_to_cstr(long number);
 *   - return NULL if the number has no assigned string.
 *
 * long wsp_string_to_foo(Octstr *ostr);
 *   - case-insensitive lookup.
 *   - Return -1 if the string has no assigned number.
 *
 * Richard Braakman
