NAME
       list_config_entries  -  Lists the names of all entries in a config sec-
       tion Allegro game programming library.

SYNOPSIS
       #include	<allegro.h>

       int list_config_entries(const char *section, const char ***names);

DESCRIPTION
       This function can be used to get	a list of all  entries	in  the	 given
       config  section.	 The  names  parameter	is  a  pointer	to an array of
       strings.	If it points to	a NULL pointer,	the list  will	be  allocated,
       else  it	 will  be  re-allocated.  You  should free the list again with
       free_config_entries if you don't	need it	anymore, or you	 can  pass  it
       again  to  list_config_entries  and the memory will be re-used. See the
       following example for how you can use it, it will print	out  the  com-
       plete contents of the current configuration:

	  int i, n;
	  char const **sections	= NULL;
	  char const **entries = NULL;

	  /* List all entries not in any section. */
	  n = list_config_entries(NULL,	&entries);
	  for (i = 0; i
	     printf(" %s=\"%s\"\n", entries[i],	get_config_string(
		    NULL, entries[i], "-"));

	  /* List all sections (and entries in them). */
	  n = list_config_sections(&sections);
	  /* loop through all section names */
	  for (i = 0; i
	  {
	     int j, m;
	     printf("%s\n", sections[i]);
	     m = list_config_entries(sections[i], &entries);
	     /*	loop through all entries in the	section	*/
	     for (j = 0; j
	     {
		 printf(" %s=\"%s\"\n",	entries[j], get_config_string(
		    sections[i], entries[j], "-"));
	     }
	  }
	  /* It	is enough to free the arrays once at the end. */
	  free_config_entries(&sections);
	  free_config_entries(&entries);

RETURN VALUE
       Returns the number of valid strings in the names	array.
