SYNOPSIS

DESCRIPTION

14       Returns a file handle to the block of memory.  All read and write oper‐
15       ations act upon the memory directly, so it must not be freed while  the
16       file remains open.
17
18       The  mode  can be any combination of “r” (readable) and “w” (writable).
19       Regardless of the mode, the file always opens at position 0.  The  file
20       size is fixed and cannot be expanded.
21
22       It  should  be closed with al_fclose(3).  After the file is closed, you
23       are responsible for freeing the memory (if needed).
