# function::kernel\_buffer\_quoted\_error(3stap)

Retrieves and quotes buffer from kernel space

## NAME

function::kernel\_buffer\_quoted\_error - Retrieves and quotes buffer from kernel space

## SYNOPSIS

```
    kernel_buffer_quoted_error:string(addr:long,inlen:long,outlen:long)
```

## ARGUMENTS

*addr*

the kernel space address to retrieve the buffer from

*inlen*

the exact length of the buffer to read

*outlen*

the maximum length of the output string

## DESCRIPTION

Reads inlen characters of a buffer from the given kernel space memory address, and returns up to outlen characters, where any ASCII characters that are not printable are replaced by the corresponding escape sequence in the returned string.
