fenv.h
Functions in this file work without the requirement for any library initialization and
only require the re-implementation of
__rt_raise() .
float.h
This file does not contain any code. The definitions in the file do not require library
initialization or function re-implementation.
inttypes.h
Functions listed in this file require the
locale functions.
limits.h
Functions in this file work without the requirement for any library initialization or
function re-implementation.
locale.h
Call
setlocale() before calling any function that uses locale functions. For example
call:
setlocale(LC_ALL, "C")
See the contents of locale.h for details of the following functions and data structures:
setlocale() Selects the appropriate locale as specified by the category and
locale arguments.
lconv Is the structure used by locale functions for formatting numeric
quantities according to the rules of the current locale.
localeconv() Creates an lconv structure and returns a pointer to it.
_get_lconv() Fills the lconv structure pointed to by the parameter. This ANSI
extension removes the requirement for static data within the
library.
locale.h also contains constant declarations used with locale functions. See Tailoring
locale and CTYPE on page 4-26 for more information.
