Ada Programming/Libraries/Ada.Storage IO

Ada.Storage_IO __TOC__ Ada Storage_IO is a unit of the Predefined Language Environment since Ada 95. Description Ada.Storage_IO is not a general-purpose Input/Output package. According to A 9 The Generic Package Storage_IO(1), it is designed for the construction of user-defined input-output packages, but may also be used to transfer elements from one task to another. Note: None of the language defined IO packages is task-safe. It allows you to store one element inside a memory buffer. The element needs to be of a definite subtype. Be careful: The exception Data_Error need not be called when the value read cannot be interpreted as a value of the subtype Element_Type (you have to follow several references given in the RM to A 13 Exceptions in Input-Output), which may lead to erroneous execution; this may especially occur if a value has never been written. Use the 'Valid attribute when not sure.
