I have need to search a= directory and return the name of the most recent file matching a given pat= tern.=C2=A0 Given a directory with these files and timestamps,

q.pat= tern1.abc Feb 13

r.pattern1.cdf=C2=A0 Feb 12

s.pattern1.e= fg=C2=A0 Feb 10
t.pattern2.abc Feb 13
u.pattern2.xyz=C2=A0 Feb 14
= v.pattern2.efg=C2=A0 Feb 10

calling my_function("/path/to= /dir", "pattern1") will return q.pattern1.abc and calling my= _function("/path/to/dir", "pattern2") will return u.pat= tern2.xyz.

My question is, what would be a reasonable behavior= /result/return value if:

1. "/path/to/dir" does not exis= t or is not readable

2. no files match the given pattern

Also, what would be a reasonable name for such a function?
