22.9.10.1. mysql_client_find_plugin()

struct st_mysql_client_plugin *mysql_client_find_plugin(MYSQL *mysql, const char *name, int type)

Description

Returns a pointer to a loaded plugin, loading the plugin first if necessary. An error occurs if the type is invalid or the plugin cannot be found or loaded.

Specify the parameters as follows:

  • mysql: A pointer to a MYSQL structure. The plugin API does not require a connection to a MySQL server, but this structure must be properly initialized. The structure is used to obtain connection-related information.

  • name: The plugin name.

  • type: The plugin type.

This function was added in MySQL 5.5.7.

Return Values

A pointer to the plugin for success. NULL if an error occurred.

Errors

To check for errors, call the mysql_error() or mysql_errno() function. See Section 22.9.3.15, “mysql_error(), and Section 22.9.3.14, “mysql_errno().

Example
MYSQL mysql;
struct st_mysql_client_plugin *p;

if ((p = mysql_client_find_plugin(&mysql, "myplugin",
                                  MYSQL_AUTHENTICATION_PLUGIN, 0)))
{
  printf("Plugin version: %d.%d.%d\n", p->version[0], p->version[1], p->version[2]);
}
