sstr
sstr_t are objects that represent sequences of characters. The standard C style string is a sequence of characters terminated by a null character, which is easy to cause buffer overflow. And it's annoying to pass pointer and length of string to every whare.
sstr_t supply a sstr_printf() function to format string.
The sequence of characters just like a string in C++, inside the sstr_t struct, it also has a null character at the end, so that we can use sstr_t as a C style string.
sstr_t contains a pointer to char sequence and its length, solves the security problems of standard C string. With functions bundle with sstr_t, you can easily manipulate the string just like standard C string, but in a safer way:
sstr_append(stotal, s1);
sstr_append_of(stotal, " ", 1);
sstr_append(stotal, s2);
sstr_free(s1);
sstr_free(s2);
stotal, stotal, 123, (long)456);
puts(sstr_cstr(result));
sstr_free(result);
sstr_free(stotal);
sstr_t sstr(const char *cstr)
Create a sstr_t from C-style (NULL-terminated) string str.
