Standard C Implementation Definition

>>& filename

This appends both

stdout

and

stderr

filename

File redirection is done only if either:

• the invoking operating system supports it

• the program reads and writes characters and has not replaced the C library

functions

fputc()

and

fgetc()

B.1.6 Floating-point

B.1.8 Registers

Using the ARM compilers, you can declare any number of local objects (auto variables)

to have the storage class

. See Variable declaration keywords on page 3-9 for

information on how the ARM compilers implements the

storage class.

B.1.9 Structures, unions, enumerations, and bitfields

The ISO/IEC C standard requires the following implementation details to be

documented for structured data types:

• the outcome when a member of a union is accessed using a member of different

type

• the padding and alignment of members of structures
