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.
