ptob(D3)

ptob -- convert size in pages to size in bytes

Synopsis

   #include <sys/types.h>
   #include <sys/ddi.h>
   
   ulong_t ptob(ulong_t numpages);

ptob returns the number of bytes that are contained in the specified number of pages.

The return value is the number of bytes in the specified number of pages.

There is no checking done on the input value and overflow is not detected.

In the case of a page count whose corresponding byte count cannot be represented by a ulong_t the higher order bits are truncated.

If the page size is 2048, then ptob(2) returns 4096. ptob(0) returns 0.
