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.
