def register_data_types_and_formats(formats):
"""
Registers multiple data types and formats at once.
To register one type/format at a time use register_custom_data_type/register_custom_data_format
It employs a special table of types and formats described below:
The 'formats' is a list of tuples. If a tuple has one element then it is the format to be registered with dtid=0
If the tuple has more than one element, then tuple[0] is the data type and tuple[1:] are the data formats. For example:
many_formats = [
(pascal_data_type(), pascal_data_format()),
(simplevm_data_type(), simplevm_data_format()),
(makedword_data_format(),),
(simplevm_data_format(),)
]
The first two tuples describe data types and their associated formats.
The last two tuples describe two data formats to be used with built-in data types.
The data format may be attached to several data types. The id of the
data format is stored in the first data_format_t object. For example:
assert many_formats[1][1] != -1
assert many_formats[2][0] != -1
assert many_formats[3][0] == -1
