Member Function Documentation

char * MP4::Box::asBox ( )

inherited

Returns a copy of the data pointer.

char* MP4::Box::asBox ( )

inherited

uint64_t MP4::Box::boxedSize ( )

inherited

uint64_t MP4::Box::boxedSize ( )

inherited

Returns the total boxed size of this box, including the header.

void MP4::Box::clear ( )

inherited

Makes this box managed if it wasn't already, resetting the internal storage to 8 bytes (the minimum).

If this box wasn't managed, the original data is left intact - otherwise it is free'd. If it was somehow impossible to allocate 8 bytes (should never happen), this will cause segfaults later.
