31 | * 32-bit st_*time fields as that is how the 32-bit GLib DLL normally |
32 | * has been compiled. If you get a compiler warning when calling |
33 | * g_stat(), do take it seriously and make sure that the type of |
34 | * struct stat the code in GLib fills in matches the struct the type |
35 | * of struct stat you pass to g_stat(). To avoid hassle, to get file |
36 | * attributes just use the GIO API instead which doesn't use struct |
37 | * stat. |
38 | * |
39 | * Sure, it would be nicer to use a struct with 64-bit st_size and |
40 | * 64-bit st_*time fields, but changing that now would break ABI. And |
41 | * in MinGW, a plain "struct stat" is the one with 32-bit st_size and |
42 | * st_*time fields. |
