NAME
     strdup, strndup -- save a copy of a string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     char *
     strdup(const char *s1);

     char *
     strndup(const char *s1, size_t n);

DESCRIPTION
     The strdup() function allocates sufficient memory for a copy of the string s1, does the
     copy, and returns a pointer to it.  The pointer may subsequently be used as an argument to
     the function free(3).

     If insufficient memory is available, NULL is returned and errno is set to ENOMEM.

     The strndup() function copies at most n characters from the string s1 always NUL terminat-
     ing the copied string.

SEE ALSO
     free(3), malloc(3)

HISTORY
     The strdup() function first appeared in 4.4BSD.  The strndup() function was added in
     FreeBSD 7.2.

• 문자열이므로 '\0'을 고려하여 strlen + 1 만큼의 크기로 메모리 할당
• 하나씩 복사한 후 마지막에 널 추가!
