11

ARGUMENTS

13       addr
14           the kernel space address to retrieve the buffer from
15
16       inlen
17           the exact length of the buffer to read
18
19       outlen
20           the maximum length of the output string

DESCRIPTION

23       Reads inlen characters of a buffer from the given kernel space memory
24       address, and returns up to outlen characters, where any ASCII
25       characters that are not printable are replaced by the corresponding
26       escape sequence in the returned string. Note that the string will be

28       is not accessible at the given address, an error is thrown.
