Subject: Figure out absolute path for the pid file before daemonizing
X-Git-Tag: hostap_0_7_0~239
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cedf947308ed26d08aec391794a16c9f8d715023;p=thirdparty%2Fhostap.git

Figure out absolute path for the pid file before daemonizing

This allows relative path to be used in the same way as was already
supported by wpa_supplicant.
