The strtoimax and strtoumax subroutines return the converted value, if any.
If no conversion could be performed, zero is returned.
If the correct value is outside the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} is returned (according to the return type and sign of the value, if any), and the errno global variable is set to ERANGE.
Converts string to integer type.
The strtoimax and strtoumax subroutines are equivalent to the strtol, strtoll, strtoul, and strtoull subroutines, except that the initial portion of the string shall be converted to intmax_t and uintmax_t representation, respectively.
