strtoimax, strtoumax

Defined in header <inttypes.h> 
intmax_t strtoimax( const char *restrict nptr,
-                    char **restrict endptr, int base );
-		 (since C99) 
uintmax_t strtoumax( const char *restrict nptr,
-                     char **restrict endptr, int base );
-		 (since C99)

Interprets an integer value in a byte string pointed to by nptr.

-

Discards any whitespace characters (as identified by calling isspace) until the first non-whitespace character is found, then takes as many characters as possible to form a valid base-n (where n=base) integer number representation and converts them to an integer value. The valid integer value consists of the following parts:

-

The set of valid values for base is {0,2,3,...,36}. The set of valid digits for base-2 integers is {0,1}, for base-3 integers is {0,1,2}, and so on. For bases larger than 10, valid digits include alphabetic characters, starting from Aa for base-11 integer, to Zz for base-36 integer. The case of the characters is ignored.

-

Additional numeric formats may be accepted by the currently installed C locale.

-

If the value of base is ​0​, the numeric base is auto-detected: if the prefix is 0, the base is octal, if the prefix is 0x or 0X, the base is hexadecimal, otherwise the base is decimal.

-

If the minus sign was part of the input sequence, the numeric value calculated from the sequence of digits is negated as if by unary minus in the result type.

-

The functions sets the pointer pointed to by endptr to point to the character past the last character interpreted. If endptr is a null pointer, it is ignored.

-

If the nptr is empty or does not have the expected form, no conversion is performed, and (if endptr is not a null pointer) the value of nptr is stored in the object pointed to by endptr.

-

Parameters

- - - -
nptr - pointer to the null-terminated byte string to be interpreted
endptr - pointer to a pointer to character.
base - base of the interpreted integer value

Return value

Example

#include <errno.h>
-#include <inttypes.h>
-#include <stdio.h>
-#include <string.h>
- 
-int main(void)
-{
-    char* endptr;
- 
-    printf("%ld\n", strtoimax(" -123junk",&endptr,10)); /* base 10                    */
-    printf("%ld\n", strtoimax("11111111",&endptr,2));   /* base 2                     */
-    printf("%ld\n", strtoimax("XyZ",&endptr,36));       /* base 36                    */
-    printf("%ld\n", strtoimax("010",&endptr,0));        /* octal auto-detection       */
-    printf("%ld\n", strtoimax("10",&endptr,0));         /* decimal auto-detection     */
-    printf("%ld\n", strtoimax("0x10",&endptr,0));       /* hexadecimal auto-detection */
- 
-    /* range error             */
-    /* LONG_MAX+1 --> LONG_MAX */
-    errno = 0;
-    printf("%ld\n", strtoimax("9223372036854775808",&endptr,10));
-    printf("%s\n", strerror(errno));
- 
-    return 0;
-}

Output:

-
-123
-255
-44027
-8
-10
-16
-9223372036854775807
-Numerical result out of range
