Converts an integer into the equivalent null-terminated, hexadecimal string and stores it.

#include <stdlib.h>

char *itoh (int n, char *buffer);

#include <wchar.h>

wchar_t *_itohw(wint n, wchar_t *buffer);
wchar_t *_witoh(wint n, wchar_t *buffer);

Parameters

n

Integer to convert.

buffer

Pointer to a string. The buffer must be large enough to hold the largest integer on the target system.

Remarks

itoh converts all non-numeric hexadecimal characters to lower case. This function also does not place a leading 0 character in the buffer.

For portability, use the sprintf %x conversion specifier.

_itohw is the wide-character version of itoh. _witoh is an alias for _itohw.

Return Values

A pointer to the converted string.
