MSP430 IAR C/C++ Compiler reference guide - Rice University

Library functionsIAR DLIB LibraryThe IAR DLIB Library provides most of the important C and C++ library definitionsthat apply to embedded systems. These are of the following types:●●●●●Adherence to a free-standing implementation of the ISO/ANSI standard for theprogramming language C. For additional information, see the chapterImplementation-defined behavior in this guide.Standard C library definitions, for user programs.Embedded C++ library definitions, for user programs.CSTARTUP, the module containing the start-up code. It is described in the chapterThe DLIB runtime environment in this guide.Runtime support libraries; for example low-level floating-point routines.● Intrinsic functions, allowing low-level use of MSP430 features. See the chapterIntrinsic functions for more information.In addition, the IAR DLIB Library includes some added C functionality, partly takenfrom the C99 standard, see Added C functionality, page 236.C HEADER FILESThis section lists the header files specific to the DLIB library C definitions. Header filesmay additionally contain target-specific definitions; these are documented in the chapterCompiler extensions.The following table lists the C header files:Header fileassert.hctype.herrno.hfloat.hinttypes.hiso646.hlimits.hlocale.hmath.hsetjmp.hsignal.hstdarg.hUsageEnforcing assertions when functions executeClassifying charactersTesting error codes reported by library functionsTesting floating-point type propertiesDefining formatters for all types defined in stdint.hUsing Amendment 1—iso646.h standard headerTesting integer type propertiesAdapting to different cultural conventionsComputing common mathematical functionsExecuting non-local goto statementsTable 40: Traditional standard C header files—DLIBControlling various exceptional conditionsAccessing a varying number of argumentsPart 2.
