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. Note that the string will be surrounded by double quotes. On the rare
       cases when kernel space data is not accessible at the given address, an error is thrown.
