NAME         top

       function::kernel_buffer_quoted_error - Retrieves and quotes
       buffer from kernel space

SYNOPSIS         top

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

ARGUMENTS         top

       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         top

       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.
