NAME

mtext_from_data - Allocate a new M-text with specified data.

SYNOPSIS

MText* mtext_from_data (const void * data, int nitems, enum MTextFormat format)

DESCRIPTION

Allocate a new M-text with specified data.

The mtext_from_data() function allocates a new M-text whose character sequence is specified by array data of nitems elements. format specifies the format of data.

When format is either MTEXT_FORMAT_US_ASCII or MTEXT_FORMAT_UTF_8, the contents of data must be of the type unsigned char, and nitems counts by byte.

When format is either MTEXT_FORMAT_UTF_16LE or MTEXT_FORMAT_UTF_16BE, the contents of data must be of the type unsigned short, and nitems counts by unsigned short.

When format is either MTEXT_FORMAT_UTF_32LE or MTEXT_FORMAT_UTF_32BE, the contents of data must be of the type unsigned, and nitems counts by unsigned.

The character sequence of the M-text is not modifiable. The contents of data must not be modified while the M-text is alive.

The allocated M-text will not be freed unless the user explicitly does so with the m17n_object_unref() function. Even in that case, data is not freed.

RETURN VALUE

If the operation was successful, mtext_from_data() returns a pointer to the allocated M-text. Otherwise it returns NULL and assigns an error code to the external variable merror_code.

ERRORS

MERROR_MTEXT
