strtoimax or strtoumax Subroutine
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.
Purpose
Converts string to integer type.
Syntax
Description
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.
Parameters
Item | Description |
---|---|
nptr | Points to the string to be converted. |
endptr | Points to the object where the final string is stored. |
base | Determines the value of the integer represented in some radix. |
