fmt_ulong0 - write a zero-padded ASCII representation of an unsigned long integer SYNTAX
#include <fmt.h> size_t fmt_ulong0(char *dest, unsigned long source, size_t n); DESCRIPTION
fmt_ulong0 writes an ASCII representation ('0' to '9', base 10) of source to dest and returns the number of bytes written. The output is padded with '0'-bytes until it encompasses at least n bytes, but it will not be truncated if it does not fit. fmt_ulong0 does not append . If dest equals FMT_LEN (i.e. is zero), fmt_ulong0 returns the number of bytes it would have written. For convenience, fmt.h defines the integer FMT_ULONG to be big enough to contain every possible fmt_ulong output plus . SEE ALSO

wcsrtombs - convert a wide character string to a multibyte string SYNOPSIS
#include <wchar.h> size_t wcsrtombs(char *dest, const wchar_t **src, size_t len, mbstate_t *ps); DESCRIPTION
If dest is not a NULL pointer, the wcsrtombs function converts the wide-character string *src to a multibyte string starting at dest. At most len bytes are written to dest. The shift state *ps is updated. The conversion is effectively performed by repeatedly calling wcr- tomb(dest,*src,ps), as long as this call succeeds, and then incrementing dest by the number of bytes written and *src by one. The conver- sion can stop for three reasons: 1. A wide character has been encountered that can not be represented as a multibyte sequence (according to the current locale). In this case *src is left pointing to the invalid wide character, (size_t)(-1) is returned, and errno is set to EILSEQ. 2. The length limit forces a stop. In this case *src is left pointing to the next wide character to be converted, and the number of bytes written to dest is returned. 3. The wide-character string has been completely converted, including the terminating L'
