|
|
|
+ * POD support routines for PhysicsFS.
|
|
|
+ *
|
|
|
+ * This driver handles Terminal Velocity POD archives.
|
|
|
+ *
|
|
|
+ * The POD format is as follows:
|
|
|
+ *
|
|
|
+ * While there is no known signature, the file starts with an
|
|
|
+ * unsigned 32-bit integer with the file count, followed by
|
|
|
+ * an 80-character, null-padded string with a description of
|
|
|
+ * the pod file. The file entries follow, and are as such:
|
|
|
+ *
|
|
|
+ * struct {
|
|
|
+ * char file_path[32]; // Full file path, IE: "ART\VGA.ACT"
|
|
|
+ * uint32_t file_size; // filesize in bytes
|
|
|
+ * uint32_t offset; // The offset of the data.
|
|
|
+ * } fileEntry_t; // Once per file. The file data itself is at offset after all entries.
|
|
|
+ *
|
|
|
+ * (This info is from: https://moddingwiki.shikadi.net/wiki/POD_Format)
|
|
|
+ *
|
|
|
+ * There are other POD file formats, but they haven't been implemented yet.
|
|
|
+ *
|
|
|
+ * Please see the file LICENSE.txt in the source's root directory.
