NAME

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

SYNOPSIS

       1) kernel_buffer_quoted:string(addr:long,inlen:long)

       2) kernel_buffer_quoted: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

       1) Reads inlen characters of a buffer from the given kernel space memory address, and
       returns up to MAXSTRINGLEN 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, the address itself is returned as a string, without
       double quotes.

       2) 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, the address itself is returned as a string, without
       double quotes.
