NAMElist_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);

DESCRIPTIONThis 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 VALUEReturns the number of valid strings in the names array.
