    strsep 库函数用于分解字符串。通常用于URL解析。

#include <string.h>

char *strsep_test(char **s, const char *ct);

int
main(int argc, char **argv)
{
    char s[] = "";
    char *ss = s;
    char *t = "/";

    printf("Result: %s\n", strsep_test(&ss, t));

    return 0;
}

char*
strsep_test(char **s, const char *ct)
{
    char *sbegin = *s;
    char *end;

    if (sbegin == NULL) {
        return NULL;
    }

    end = strpbrk(sbegin, ct);
    if (end) {
        *end++ = '\0';
    }
    *s = end;

    return sbegin;
}
