Memfile interface
The memfile interface allows you to treat a fixed block of contiguous memory as a file that can be used with Allegro's I/O functions.
These functions are declared in the following header file. Link with allegro_memfile.
#include <allegro5/allegro_memfile.h>al_open_memfile
ALLEGRO_FILE *al_open_memfile(void *mem, int64_t size, const char *mode)
ALLEGRO_FILE *al_open_memfile(void *mem, int64_t size, const char *mode)
ALLEGRO_FILE *al_open_memfile(void *mem, int64_t size, const char *mode)Returns a file handle to the block of memory. All read and write operations act upon the memory directly, so it must not be freed while the file remains open.
The mode can be any combination of "r" (readable) and "w" (writable). Regardless of the mode, the file always opens at position 0. The file size is fixed and cannot be expanded. The file is always read from/written to in binary mode, which means that no newline translation is performed.
It should be closed with al_fclose. After the file is closed, you are responsible for freeing the memory (if needed).
al_get_allegro_memfile_version
uint32_t al_get_allegro_memfile_version(void)
uint32_t al_get_allegro_memfile_version(void)
uint32_t al_get_allegro_memfile_version(void)Returns the (compiled) version of the addon, in the same format as al_get_allegro_version.
