FUNCTION::KERNELBUF(3stString and data retrieving FUNCTION::KERNELBUF(3stap)

NAME
       function::kernelbufferquotederror - Retrieves and quotes buffer from
       kernel space

SYNOPSIS
           kernelbufferquotederror: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.
