# 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 some_symbol 0x1000 PROT_NONE
## Usage:
```bash
usage: mprotect [-h] addr length prot
```
