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. */ |
