page_size(9v)page_size(9v)NAME
page_size - Global Variable: Is the virtual page size
SYNOPSIS
extern vm_size_t page_size;
DESCRIPTION
The page_size global variable is the size of a virtual page on a CPU. A device driver can use this global variable to partition I/O trans-
fers so that they never cross a virtual page boundary. You should use this global variable only when: A subsystem cannot use the DMA map-
ping routines (such as, dma_map_alloc, dma_map_load, and so forth) There is a one-to-one correspondence between the system memory map and
the I/O's view of the system memory space

METHODS

o $value (double)
o $lower (double)
o $upper (double)
o $step_increment (double)

o $value (double)
o $lower (double)
o $upper (double)
o $step_increment (double)
o $page_increment (double)
o $page_size (double)
Since: gtk+ 2.14
$adjustment->set_lower ($newval)
$adjustment->set_page_increment ($newval)
$adjustment->set_page_size ($newval)
$adjustment->set_step_increment ($newval)
$adjustment->set_upper ($newval)
o $newval (double)
These functions differ from the plain "->lower" etc setters in that they emit "notify" and "changed" signals if $newval is different from
the current value.
The corresponding "get_lower" etc are not wrapped because they're the same as the "lower" etc field accessors above.
Since: gtk+ 2.14
double = $adjustment->value
double = $adjustment->value ($newval)
double = $adjustment->lower
double = $adjustment->lower ($newval)
double = $adjustment->upper
double = $adjustment->upper ($newval)
double = $adjustment->step_increment
double = $adjustment->step_increment ($newval)
double = $adjustment->page_increment
double = $adjustment->page_increment ($newval)
double = $adjustment->page_size
double = $adjustment->page_size ($newval)
o $newval (double)
Get or set the six fields of a Gtk2::Adjustment.
The setter functions store $newval and return the old value. Note that they don't emit any signals; it's up to you to emit "notify"
(because the fields are also properties) and "changed" or "value-changed", when you're ready.
