# mprotect
|
|
|
|
## Description
|
|
|
|
|
|
|
|
Calls the mprotect syscall and prints its result value.
|
|
|
|
Note that the mprotect syscall may fail for various reasons
|
|
(see `man mprotect`) and a non-zero error return value
|
|
can be decoded with the `errno <value>` command.
|
|
|
|
Examples:
|
|
mprotect $rsp 4096 PROT_READ|PROT_WRITE|PROT_EXEC
|
|
mprotect $rsp 4096 rwx
|
|
mprotect $rsp 4096 7
|
|
mprotect some_symbol 0x1000 PROT_NONE
|
|
|
|
## Usage:
|
|
|
|
|
|
```bash
|
|
usage: mprotect [-h] addr length prot
|
|
|
|
```
