# m17nObject(3m17n)

\- Objects managed by the reference count

## NAME

m17nObject\_-\_Managed\_Ob -  - Objects managed by the reference count \

## SYNOPSIS

### Data Structures

struct **M17NObjectHead**\
 The first member of a managed object.

### Functions

void \* **m17n\_object** (int size, void(\*freer)(void \*))\
 int **m17n\_object\_ref** (void \*object)\
 Increment the reference count of a managed object.  int **m17n\_object\_unref** (void \*object)\
 Decrement the reference count of a managed object.

## Detailed Description

Objects managed by the reference count \

Managed objects are objects managed by the reference count.

There are some types of m17n objects that are managed by their reference count. Those objects are called *managed* *objects*. When created, the reference count of a managed object is initialized to one. The **m17n\_object\_ref()** function increments the reference count of a managed object by one, and the **m17n\_object\_unref()** function decrements by one. A managed object is automatically freed when its reference count becomes zero.

A property whose key is a managing key can have only a managed object as its value. Some functions, for instance **msymbol\_put()** and **mplist\_put()**, pay special attention to such a property.

In addition to the predefined managed object types, users can define their own managed object types. See the documentation of the **m17n\_object()** for more details. \
