Subject: Disabling interrupts to protect data

Hi Guys,

I am working on some RTOS, in which I see lot of interrupts "enabling"
and "disabling" code in most of the RTOS API's to protect kernel data.
For example, Semaphore API's, Message Queue APIs, Runtime memory
management API's. Is enabling / disabling interrupts only way to
protect
the kernel data? Why  I am asking this is whenever interrupts are
disabled, I am scared of losing timer interrupts. Any input is
appreciated?

Regards,
Kiran
