# mdatabase\_load(3m17n)

## NAME

mdatabase\_load -

## SYNOPSIS

void\* **mdatabase\_load** (**MDatabase** \* *mdb*)

## DESCRIPTION

Load a data from the database. The **mdatabase\_load()** function loads a data specified in **mdb** and returns the contents. The type of contents depends on the type of the data.

If the data is of the *plist* *type*, this function returns a pointer to *plist*.

If the database is of the *chartable* *type*, it returns a chartable. The default value of the chartable is set according to the second tag of the data as below:

- •

  If the tag is **Msymbol**, the default value is **Mnil**.

- •

  If the tag is **Minteger**, the default value is -1.

- •

  Otherwise, the default value is `NULL`.

If the data is of the *charset* *type*, it returns a plist of length 2 (keys are both **Mt**). The value of the first element is an array of integers that maps code points to the corresponding character codes. The value of the second element is a chartable of integers that does the reverse mapping. The charset must be defined in advance. \
