anywhere (except here).
|

PT_PROT allows one to enable/disable the data memory break bit

for pages of memory in an inferior process. This bit is used
|
||||
to cause "Data memory break traps" to occur when the appropriate
|
||||
page is written to.
|
||||
|
||||
The arguments are as follows:
|
||||
|
||||
PT_PROT -- The ptrace action to perform.
|
||||
|
||||
INFERIOR_PID -- The pid of the process who's page table entries
|
||||
will be modified.
|
||||
|
||||
PT_ARGS -- The *address* of a 3 word block of memory which has
|
||||
additional information:
|
||||
|
||||
word 0 -- The start address to watch. This should be a page-aligned
|
||||
address.
|
||||
|
||||
word 1 -- The ending address to watch. Again, this should be a
|
||||
page aligned address.
|
||||
|
||||
word 2 -- Nonzero to enable the data memory break bit on the
|
||||
given address range or zero to disable the data memory break
|
||||
bit on the given address range.
|
||||
|
||||
This call may fail if the given addresses are not valid in the inferior
|
||||
process. This most often happens when restarting a program which
|
||||
has watchpoints inserted on heap or stack memory. */
