C in a Nutshell

Name

wcstoimax

Synopsis

Converts a wide string into an integer value with type intmax_t

#include <stddef.h>
#include <inttypes.h>
intmax_twcstoimax( const wchar_t * restrict wcs,
                    wchar_t ** restrict endptr, int base );

The wcstoimax() function is similar to wcstol(), except that it converts a wide string to an integer value of type intmax_t. If the conversion fails, wcstoimax() returns 0. If the result of the conversion exceeds the range of the type intmax_t, then the wcstoimax() returns INTMAX_MAX or INTMAX_MIN, and sets the errno variable to the value of ERANGE (“range error”).

Example

See the example for the analogous function wcstoumax() in this chapter.
