Standard C Implementation Definition B.1 Implementation definition Appendix G of the ISO C standard (ISO/IEC 9899:1990 (E)) collates information about portability issues. Sub-clause G3 lists the behavior that each implementation must document. Note This appendix does not duplicate information that is part of Chapter 4 Compiler-specific Features. This appendix provides references where applicable. The following subsections correspond to the relevant sections of sub-clause G3. They describe aspects of the ARM C compiler and C library, not defined by the ISO C standard, that are implementation-defined: Note The support for the wctype.h and wchar.h headers excludes wide file operations.

Standard C Implementation Definition B.1.1 Translation Diagnostic messages produced by the compiler are of the form: source-file, line-number: severity: error-code: explanation where severity is one of: [blank] Warning Error If the severity is blank, this is a remark and indicates common, but sometimes unconventional, use of C or C++. Remarks are not displayed by default. Use the --remarks option to display remark messages. See Controlling the output of diagnostic messages on page 5-4 for more information. Compilation continues. Flags unusual conditions in your code that might indicate a problem. Compilation continues. Indicates a problem that causes the compilation to stop. For example, violations in the syntactic or semantic rules of the C or C++ language. Internal fault Indicates an internal problem with the compiler. Contact your supplier with the information listed in Feedback on page x. Here: error-code Is a number identifying the error type. explanation Is a text description of the error. See Chapter 5 Diagnostic Messages in the Compiler User Guide for more information. B.1.2 Environment The mapping of a command line from the ARM architecture-based environment into arguments to main() is implementation-specific. The generic ARM C library supports the following: • main() • Interactive device on page B-4 • Redirecting standard input, output, and error streams on page B-4. main() The arguments given to main() are the words of the command line not including input/output redirections, delimited by whitespace, except where the whitespace is contained in double quotes.
