ptob(D3)

NAME
     ptob - convert size in pages to size in bytes

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

   Arguments
     numpages  Size in pages to convert to equivalent size in bytes.

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

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

USAGE
     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.

   Level
     Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

     Driver-defined basic locks, read/write locks, and sleep locks may be held
     across calls to this function.

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