int afReadMisc (AFfilehandle file, int miscid, void *buffer, int nbytes);
int afWriteMisc (AFfilehandle file, int miscid, const void *buffer, int nbytes);
int afSeekMisc (AFfilehandle file, int miscid, int offbytes);
afReadMisc reads up to nbytes from the miscellaneous data chunk identified by miscid in file.
afWriteMisc writes up to nbytes to the miscellaneous data chunk identified by miscid in file.
afSeekMisc changes the current offset within the miscellaneous data chunk identified by miscid to the offset offbytes.
afReadMisc returns the number of bytes read from the specified miscellaneous chunk into the buffer referred to by buffer.
afWriteMisc returns the number of bytes written to the specified miscellaneous chunk from the buffer referred to by buffer.
afSeekMisc returns the new location of the logical data pointer as measured as an offset in bytes from the beginning of the miscellaneous chunk's data area.
afReadMisc, afWriteMisc, and afSeekMisc can produce the following error codes:
AF_BAD_READ
AF_BAD_WRITE
AF_BAD_MISCSEEK
AF_BAD_MISCID
AF_BAD_TRACKID
AF_BAD_FILEHANDLE
