Subject: int_array: Add a function to check for equality
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=56f7d76d745addac7666e8e5c0bd4ac84c902f5e;p=thirdparty%2Fhostap.git

int_array: Add a function to check for equality

Add int_array_equal() to allow comparison of two int_array
instances. Return true if both arrays included the same set of integers.
