These variables can be read and in some cases\nmodified using the /proc filesystem, and the (deprecated) sysctl(2) system call.\n\nString values may be terminated by either '\\0' or '\\n'.\n\nInteger  and  long  values may be written either in decimal or in hexadecimal notation\n(e.g., 0x3FFF).  When writing multiple integer or long values, these may be  separated\nby  any of the following whitespace characters: ' ', '\\t', or '\\n'.  Using other sepa‐\nrators leads to the error EINVAL.\n",
