IAR CLIB Librarystdio.hIn stdio.h, the following C99 functions are defined:vscanf, vfscanf, vsscanf, vsnprintf, snprintfThe functions printf, scanf, and all their variants have added functionality from theC99 standard. For reference information about these functions, see the library referenceavailable from the Help menu.The following functions providing I/O functionality for libraries built without FILEsupport are definded:__write_array Corresponds to fwrite on stdout.__ungetchar__getsCorresponds to ungetc on stdout.Corresponds to fgets on stdin.stdlib.hIn stdlib.h, the following C99 functions are defined:_Exit, llabs, lldiv, strtoll, strtoull, atoll, strtof, strtold.The function strtod has added functionality from the C99 standard. For referenceinformation about this functions, see the library reference available from the Helpmenu.The __qsortbbl function is defined; it provides sorting using a bubble sort algorithm.This is useful for applications that have a limited stack.wchar.hIn wchar.h, the following C99 functions are defined:vfwscanf, vswscanf, vwscanf, wcstof, wcstolb.wctype.hIn wctype.h, the C99 function iswblank is defined.IAR CLIB LibraryThe IAR CLIB Library provides most of the important C library definitions that applyto embedded systems. These are of the following types:●Standard C library definitions available for user programs. These are documented inthis chapter.238MSP430 IAR C/C++ CompilerReference Guide
