wcstoumax - convert wide character string to integer of type uintmax_t

Syntax	#include <inttypes.h> uintmax_t wcstoumax(const wchar_t * nptr, wchar_t ** endptr, int base);
Description	wcstoumax() converts the initial portion of the wide character string pointed to by nptr to uintmax_t representation. uintmax_t is a type predefined in stdint.h: typedef unsigned long long uintmax_t; For more descrition see wcstoull().
Return val.	converted value
		if successful.
	0	if no conversion could be performed. errno is set to indicate an error .
	UINTMAX_MAX
		if the correct value is outside the range of representable values. errno is set to indicate an error .
Errors	wcstoumax() will fail if:
	EINVAL	The value of base is not supported.
	ERANGE	The correct value is outside the range of representable values.
