list_config_entries(3)          Allegro manual          list_config_entries(3)

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\"\n", entries[i], get_config_string(
                    NULL, entries[i], "-"));

          /* List all sections (and entries in them). */
          n = list_config_sections(§ions);
          /* 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(§ions);
          free_config_entries(&entries);

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