The header <malloc.h> declares several memory management functions, several mallopt
argument macros and a structure returned by the mallinfo function. The following
identifiers are declared in this header file:
NOTE This header file is not defined by the ANSI C standard. Programs using this
header are likely to be less portable.
Math Library <math.h>
The header <math.h> contains declarations for all functions in the HP C/iX math library.
It contains various function declarations for routines in the standard library that return
floating-point values.
The header also defines structures and constants used by the matherr error-handling
mechanisms, and macros provided for compatibility with other implementations.
lconv type definition A structure type definition for a record containing numeric
and monetary formatting values. See the description of the
localeconv function for more details.
localeconv() function Returns information about the editing symbols of a numeric
quantity specific to a locale.
NULL macro The constant 0.
setlocale() function Controls locale-specific features of the library.
