_ultoa, _ultow
Visual Studio .NET 2003
Convert an unsigned long integer to a string.
char *_ultoa( unsigned long value, char *string, int radix ); wchar_t *_ultow( unsigned 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 _ultoa function converts value to a null-terminated character string and stores the result (up to 33 bytes) in string. No overflow checking is performed. radix specifies the base of value; radix must be in the range 2 – 36. _ultow is a wide-character version of _ultoa.
