Subject: Use plugin_thread_create() rather than pthread_create() in all plugins.
X-Git-Tag: collectd-5.2.0~20^2~11
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=76e6392863d130ceca048eb860e4db1c9e40fee7;p=collectd.git

Use plugin_thread_create() rather than pthread_create() in all plugins.

This function copies the plugin context from the calling thread to the new
thread. While this might not strictly be necessary in most/many cases, this
will make sure that any code within a plugin uses the same context
information, thus avoiding possible problems in the future.
