list_config_entries(3alleg4)					  Allegro manual				      list_config_entries(3alleg4)

NAME
       list_config_entries - Lists the names of all entries in a config section 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 complete 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"
", 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
", sections[i]);
	     m = list_config_entries(sections[i], &entries);
	     /* loop through all entries in the section */
	     for (j = 0; j
	     {
		 printf(" %s="%s"
", 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.
