This function writes data of the specified size beginning at the current location of the file pointer. When the specified size is greater than the available memory, data is written until the available memory is used up. The size of the written data is returned. Depending on the implementation of the archive, the size may be expanded automatically.
This function cannot be called from the interrupt handler (IRQ mode).
Also note that in some cases processing may not end if interrupts are left prohibited.
