fyi. These two allocations could be combined into one. For example: https://github.com/epics-base/epics-base/blob/e4fbd83c93a68a1d9cb863ff341735388d246347/modules/libcom/src/iocsh/afterIocRunning.c#L62-L65
const size_t cmd_len = strlen(cmd) + 1;
struct cmditem *const item = mallocMustSucceed(sizeof(struct cmditem) + cmd_len, "afterIocRunning");
item->cmd = (char *)(item + 1);
memcpy(item->cmd, cmd, cmd_len);
Also, iteration could be done in a more compact fashion: https://github.com/epics-base/epics-base/blob/e4fbd83c93a68a1d9cb863ff341735388d246347/modules/libcom/src/iocsh/initHooks.c#L64-L65
for(cur = ellFirst(&functionList); cur; cur = ellNext(cur)) {
const initHookLink *fn = CONTAINER(cur, initHookLink, node);

Do we need this lock/unlock?

Outdated

I think this iteration can more cleanly be done over the list as opposed to over the count and selecting the N-th element; this makes it an N^2 iteration over the list instead of a one-time pass.

I don't love the variable name temp
; envptr
was better, and penvvar
or somethign would be better yet (and more consistent; see how ellFirst
/ellNext
is used in EPICS base)

string_list_t *envptr = CONTAINER(env, string_list_t, node);
CONTAINER
comes from dbDefs.h
, and is intended for these structure "base" to "derived" casts.

Lots of duplication in this loop and in the one for exclude patterns, just a thought...

I see that this change has addressed my previous comment about the loop iteration. Consider squashing these two commits?
NOTE: #112 needs to be merged first
