## Name
get\_process\_name - get the process name
## Synopsis
```**c++
#include <unistd.h>
int get_process_name(char* buffer, int buffer_length);
```
## Description
`get_process_name()` places the current process name into the provided `buffer`.
## Pledge
In pledged programs, the `stdio` promise is required for this system call.
## Errors
* `EFAULT`: the process name could not be copied into the buffer.
* `ENAMETOOLONG`: `buffer_length` is too short.
## See also
* [`set_process_name`(2)](../man2/set_process_name.md)
