I am stumped, could I get some help in understanding some code?
Referring to /usr/src/sys/kern/kern_exec.c, in the execve() code, there's
a line like:
/*
* Loop through list of image activators, calling each one.
* If there is no match, the activator returns -1. If there
* is a match, but there was an error during the activation,
* the error is returned. Otherwise 0 means success. If the
* image is interpreted, loop back up and try activating
* the interpreter.
*/
for (i = 0; execsw[i]; ++i) {
if (execsw[i]->ex_imgact)
error = (*execsw[i]->ex_imgact)(imgp);
else
continue;
(I'd give the line numbers, but Bruce has just made some changes in this
file, and ctm hasn't updated me yet. It's about line 192)
I can't figure out where the execsw array gets built. Could someone
point me at the right file?
