Description
When I try to connect to mariadb server with program linked with libmariadbclient.a over local connection, then it reports:
mysql_real_connect:Can't connect to local MySQL server through socket '/tmp/mysql.sock'
My mysql setup in /etc/mysql/my.cnf uses:
socket = /run/mysqld/mysqld.sock
for [client] and [mysqld] section.
Howto setup connection in C program to use default socket path from
/etc/mysql/my.cnf ?

Neither libmysql or libmariadb read from configuration file by default.
To read configuration options from my.cnf you need to set option MYSQL_READ_DEFAULT_GROUP:
mysql_options(mysql, MYSQL_READ_DEFAULT_GROUP, "client");

Merge request on the topic submitted downstream: https://salsa.debian.org/mariadb-team/mariadb-connector-c/merge_requests/2
I found the solution:
I need to read config file with:
mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, path);
Howto find what is the default setup path?
Do I need to manually chek if /etc/my.cnf or /etc/mysql/my.cnf or there is
better way to read my.cnf from default config directory?
