_ltoa, _ltow
Convert a long integer to a string.
char *_ltoa( long value, char *string, int radix ); wchar_t *_ltow( long value, wchar_t *string, int radix );
Parameters
- value
- Number to be converted.
- string
- String result.
- radix
- Base of value.
Return Value
Each of these functions returns a pointer to string. There is no error return.
Remarks
The _ltoa function converts the digits of value to a null-terminated character string and stores the result (up to 33 bytes) in string. 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.
