Subject: Changed return type of sread() and swrite() from 'ssize_t' to 'int'
X-Git-Tag: collectd-5.8.0~42^2
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=c84ce4c2d974d891712f0287932f57ed7e6be98d;p=collectd.git

Changed return type of sread() and swrite() from 'ssize_t' to 'int'

Functions 'sread()' and 'swrite()', unlike 'read()' and 'write()', does not return the number of bytes actually read/written.
They return error status, which is returned as 'int' type in Collectd code.
