list_config_entries — Lists the names of all entries in a config section Allegro game programming library.


#include <allegro.h>

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


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(&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. */

Return Value

Returns the number of valid strings in the names array.
