Subject: confstr.3: Rename 'len' to 'size'
X-Git-Tag: man-pages-6.00~131
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c92774db7ea2afd75d3574ae2f2fe50e0158ef22;p=thirdparty%2Fman-pages.git

confstr.3: Rename 'len' to 'size'

The parameter doesn't represent a string length (strlen(3)), but a
buffer size (sizeof()).  Use a more proper name.
