Mimic Python's strip() function in C

Question

I started on a little toy project in C lately and have been scratching my head over the best way to mimic the strip() functionality that is part of the python string objects

Answer 1

There is no standard C implementation for a strip() or trim() function. That said, here's the one included in the Linux kernel:

char *strstrip(char *s)
{
        size_t size;
        char *end;

        size = strlen(s);

        if (!size)
                return s;

        end = s + size - 1;
        while (end >= s && isspace(*end))
                end--;
        *(end + 1) = '\0';

        while (*s && isspace(*s))
                s++;

        return s;
}
