Converts a long integer to a string. More secure versions of these functions are available; see _ltoa_s, _ltow_s.

char *_ltoa(
   long value,
   char *str,
   int radix 
);
wchar_t *_ltow(
   long value,
   wchar_t *str,
   int radix 
);
template <size_t size>
char *_ltoa(
   long value,
   char (&str)[size],
   int radix 
); // C++ only
template <size_t size>
wchar_t *_ltow(
   long value,
   wchar_t (&str)[size],
   int radix 
); // C++ only

Параметры

value
Number to be converted.
str
String result.
radix
Base of value.

Возвращаемое значение

Each of these functions returns a pointer to str. There is no error return.

Заметки

The _ltoa function converts the digits of value to a null-terminated character string and stores the result (up to 33 bytes) in str. The radix argument specifies the base of value, which must be in the range 2 – 36. If radix equals 10 and value is negative, the first character of the stored string is the minus sign (–). _ltow is a wide-character version of _ltoa; the second argument and return value of _ltow are wide-character strings. Each of these functions is Microsoft-specific.

Примечание о безопасности.
To prevent buffer overruns, ensure that the str buffer is large enough to hold the converted digits plus the trailing null-character and a sign character.
