4.3 Data Types

The mailfromd filter script language operates on entities of two types: numeric and string.

The numeric type is represented internally as a signed long integer. Depending on the machine architecture, its size can vary. For example, on machines with Intel-based CPUs it is 32 bits long.

A string is a string of characters of arbitrary length. Strings can contain any characters except ASCII NUL.

There is also a generic pointer, which is designed to facilitate certain operations. It appears only in body handler. See body handler, for more information about it.
