 * nd_syscalls.stp is a copy of syscalls.stp, modified to refer to
 * function arguments by number rather than name, so that this tapset
 * can be used even when the probed kernel lacks debugging information.
 *
 * So far, the names-to-numbers conversion covers only syscall.a*
 * through syscall.c*, plus a few others.
 */


/* Each syscall returns the calls parameters. In addition, the following
* variables are set:
*
* name - generally the syscall name minus the "sys_".
*
* argstr - a string containing the decoded args in an easy-to-read format.
*          It doesn't need to contain everything, but should have all the
*          important args. Set in entry probes only. Values enclosed in
*          square brackets are user-space pointers. Values in curly
*          braces are decoded structs.
*
* retstr - a string containing the return value in an easy-to-read format.
*          Set in return probes only.
