| .TH ARES_REINIT 3 "12 November 2023" |
| .SH NAME |
| ares_reinit \- ReInitialize a resolver channel from system configuration. |
| .SH SYNOPSIS |
| .nf |
| #include <ares.h> |
| |
| int ares_reinit(ares_channel_t *\fIchannel\fP) |
| .fi |
| .SH DESCRIPTION |
| The \fBares_reinit(3)\fP function re-reads the system configuration and safely |
| applies the configuration to the existing channel. System configuration will |
| never override user-provided settings such as provided via |
| \fBares_init_options(3)\fP or \fBares_set_servers(3)\fP. |
| |
| Any existing queries will be automatically requeued if the server they are |
| currently assigned to is removed from the system configuration. |
| |
| This function may cause additional file descriptors to be created, and existing |
| ones to be destroyed if server configuration has changed. If this is called from |
| a thread other than which the main program event loop is running, care needs to |
| be taken to ensure any file descriptor lists are updated immediately within |
| the eventloop. |
| |
| .SH RETURN VALUES |
| \fIares_reinit(3)\fP can return any of the following values: |
| .TP 14 |
| .B ARES_SUCCESS |
| Initialization succeeded. |
| .TP 14 |
| .B ARES_EFILE |
| A configuration file could not be read. |
| .TP 14 |
| .B ARES_ENOMEM |
| The process's available memory was exhausted. |
| |
| .SH AVAILABILITY |
| This function was first introduced in c-ares version 1.22.0. |
