a0UseFormats()

Initialize Formats Extension.

Syntax

a0tError a0UseFormats( void );

Description

This function initializes the Formats extension library. It must be called before any other call of this library.

It defines all basic formats descriptors of Athapascan-0. They can be used to produce new complex formats of type map or function. The basic formats are as follows:

A0FChar: Character
A0FShort: Short integer
A0FInt: Integer
A0FLong: Long integer
A0FUChar: Unsigned char
A0FUShort: Unsigned short
A0FUInt: Unsigned integer
A0FULong: Unsigned long integer
A0FFloat: Floating point
A0FDouble: Double floating point
A0FLDouble: Long double floating point
A0FByte: Byte
A0FPort: Port descriptor
A0FDMARegion: DMA region descriptor

The programmer must pass those formats directly to any function. They are macros that expand to a pointer to a format (a0tFormat *).

Return Values

If an error condition occurs, it returns the error code, otherwise it returns A0ErrOk. Possible values are as follows:

Error Code	Description
`A0Err...`	Some error occurred.
`A0ErrOk`	Successful completion.
