UNIV_INTERN void* os_mem_alloc_large ( ulint *  n)

Allocates large pages memory.

allocated memory in/out: number of bytes
UNIV_INTERN void os_mem_free_large ( void *  ptr,
ulint  size 

Frees large pages memory. in: size returned by os_mem_alloc_large()

ptrin: pointer returned by os_mem_alloc_large()
UNIV_INTERN ulint os_proc_get_number ( void  )

Converts the current process id to a number. It is not guaranteed that the number is unique. In Linux returns the 'process number' of the current thread. That number is the same as one sees in 'top', for example. In Linux the thread id is not the same as one sees in 'top'.
