Function Documentation

minimal_chassis_deinit()

bool minimal_chassis_deinit	(	mysql_service_registry_t *	registry,
		mysql_component_t *	comp_ref
	)

This is the exit function for minimal_chassis static library, which has to be called just before the exit of the application.

Releases the service registry and dynamic loader services. Releases the registry handle, which is acquired at the time of minimal_chassis_init(), if provided the handle address. And un-registers the component services, if provided component reference which is statically linked to this library.

Parameters

[in]	registry	A service handle to registry service.
[in]	comp_ref	A component structure referance name.

Returns

Status of performed operation

Return values

false	success
true	failure

minimal_chassis_init()

bool minimal_chassis_init	(	mysql_service_registry_t **	registry,
		mysql_component_t *	comp_ref
	)

This is the entry function for minimal_chassis static library, which has to be called by the application code.

Bootstraps service registry and dynamic loader. And registry handle will be assigned, if provided empty handle address. And loads provided component services into the registry, if provided component reference which is statically linked to this library.

Parameters

[out]	registry	A service handle to registry service.
[in]	comp_ref	A component structure referance name.

Returns

Status of performed operation

Return values

false	success
true	failure

minimal_chassis_services_refresh()

void minimal_chassis_services_refresh

(

bool

use_related

)

This function refreshes the global service handles based on the use_related flag.

The global services are mysql_runtime_error, mysql_psi_system_v1 and mysql_rwlock_v1. If the use_related is ON then the globals are loaded with minimal chassis service implementations else they are loaded with the default service implementations

Parameters

use_related

Used to decide which service implementation to load for globals.

mysql_components_handle_std_exception()

void mysql_components_handle_std_exception

(

const char *

funcname

)

Checks if last thrown exception is any kind of standard exceptions, i.e.

the exceptions inheriting from std::exception. If so, reports an error message that states exception type and message. On any other thrown value it just reports general error.

Parameters

funcname

Name of the function where the error occurs.
