| .TH ARES_SAVE_OPTIONS 3 "1 June 2007" |
| .SH NAME |
| ares_save_options \- Save configuration values obtained from initialized ares_channel |
| .SH SYNOPSIS |
| .nf |
| .B #include <ares.h> |
| .PP |
| .B void ares_save_options(ares_channel \fIchannel\fP, struct ares_options *\fIoptions\fP, int *\fIoptmask\fP) |
| .fi |
| .SH DESCRIPTION |
| The \fBares_save_options(3)\fP function saves the channel data identified by |
| .IR channel , |
| into the options struct identified by |
| .IR options , |
| and saves the mask of options which are set to the integer |
| pointer (passed by reference) identified by |
| .IR optmask . |
| |
| The resultant options and optmask are then able to be |
| passed directly to ares_init_options. When the options |
| are no longer needed, ares_destroy_options should be called |
| to free any associated memory. |
| .SH NOTE |
| Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it |
| won't be extended to cover new funtions. This function will remain |
| functioning, but it can only return config data that can be represented in |
| this config struct, which may no longer be the complete set of config |
| options. \fBares_dup(3)\fP will not have that restriction. |
| .SH SEE ALSO |
| .BR ares_destroy_options (3), |
| .BR ares_init_options (3), |
| .BR ares_dup (3) |
| .SH AVAILABILITY |
| ares_save_options(3) was added in c-ares 1.4.0 |
