strtoumax - convert string to integer (uintmax_t)

Syntax	#include <inttypes.h> uintmax_t strtoumax(const char *s, char ** zg, int base);
Description	strtoumax() converts the EBCDIC string to which s points into an integer of type uintmax_t. uintmax_t is a type predefined in the header stdint.h: typedef unsigned long long uintmax_t; Further description see strtoull().
Return val.	Integer value of type uintmax_t
		for strings that have a structure as described for strtoull() and which represent a numeric value.
	0	for strings that do not conform to the syntax described for strtoull(). The conversion is not executed. If the value of base is not supported, errno is set to EINVAL.
	UINTMAX_MAX
		if the result overflows, depending on the sign. errno is set to ERANGE.
