Heya Brady, please use code tags for code, output, or any other kind structured text.
But figure yourself: Compared to:
For the future, thank you.
Hope this helps
EDIT:
Explanation:
This will look all files/folders (item) of check_path - if it can read from there at all, and if an entry is found named AM017Q it will print yay and break the loop.

Just a quick question:
if I want to do a comparison with a wildcard in a shell script, do i just use '*'? Heres what I have:
elif ; then

pcq_get
PCQ(9) BSD Kernel Developer's Manual PCQ(9)NAME
pcq -- producer/consumer queue
SYNOPSIS
#include <sys/pcq.h>
pcq_t *
pcq_create(size_t maxlen, km_flags_t kmflags);
void
pcq_destroy(pcq_t *pcq);
void *
pcq_get(pcq_t *pcq);
size_t
pcq_maxitems(pcq_t *pcq);
void *
pcq_peek(pcq_t *pcq);
bool
pcq_put(pcq_t *pcq, void *item);
DESCRIPTION
The machine-independent pcq interface provides lockless producer/consumer queues. A queue (pcq_t) allows multiple writers (producers), but
only a single reader (consumer). The consumer is expected to be protected by a lock that covers the structure that the pcq_t is embedded
into (e.g., socket lock, ifnet hwlock). These queues operate in a first-in, first-out (FIFO) manner. The act of inserting or removing an
item from a pcq_t does not modify the item in any way. pcq does not prevent an item from being inserted multiple times into a single pcq_t.
FUNCTIONS
pcq_create(maxlen, kmflags)
Create a queue that can store at most maxlen items at one time. kmflags should be either KM_SLEEP, if pcq_create() is allowed to
sleep until resources are available, or KM_NOSLEEP if it should return NULL immediately, if resources are unavailable.
pcq_destroy(pcq)
Free the resources held by pcq.
pcq_get(pcq)
Remove the next item to be consumed from the queue and return it. If the queue is empty, return NULL. The caller must prevent con-
current gets from occuring.
pcq_maxitems(pcq)
Return the maximum number of items that the queue can store at any one time.
pcq_peek(pcq)
Return the next item to be consumed from the queue but do not remove it from the queue. If the queue is empty, return NULL.
pcq_put(pcq, item)
Place an item at the end of the queue. If there is no room in the queue for the item, return false; otherwise, return true. The
item must not have the value of NULL.
CODE REFERENCES
The pcq interface is implemented within the file sys/kern/subr_pcq.c.
SEE ALSO atomic_ops(3), queue(9)HISTORY
The pcq interface first appeared in NetBSD 6.0.
