这是一个使用GLib / GIO获取所需信息的示例。
#include <gio/gio.h>#include <stdio.h>intmain (int argc, char **argv){ g_thread_init (NULL); g_type_init (); if (argc < 2) return -1; GError *error; GFile *file = g_file_new_for_path (argv[1]); GFileInfo *file_info = g_file_query_info (file, "standard::*", 0, NULL, &error); const char *content_type = g_file_info_get_content_type (file_info); char *desc = g_content_type_get_description (content_type); GAppInfo *app_info = g_app_info_get_default_for_type ( content_type, FALSE); GIcon *icon = g_file_info_get_icon (file_info); printf ("File: %snDescription: %snDefault Application: %sn", argv[1], desc, g_app_info_get_executable (app_info)); return 0;}
