There are two string datatypes: svn_string_t and svn_stringbuf_t. The former is a simple pointer/length pair useful for passing around strings (or arbitrary bytes) with a counted length. svn_stringbuf_t is buffered to enable efficient appending of strings without an allocation and copy for each append operation.
svn_string_t contains a const char * for its data, so it is most appropriate for constant data and for functions which expect constant, counted data. Functions should generally use const svn_string_t * as their parameter to indicate they are expecting a constant, counted string.
svn_stringbuf_t uses a plain char * for its data, so it is most appropriate for modifiable data.
Invariants
1. Null termination:
Both structures maintain a significant invariant:
s->data[s->len] == '\0'
The functions defined within this header file will maintain the invariant (which does imply that memory is allocated/defined as len+1 bytes). If code outside of the svn_string.h functions manually builds these structures, then they must enforce this invariant.
Note that an svn_string(buf)_t may contain binary data, which means that strlen(s->data) does not have to equal s->len. The null terminator is provided to make it easier to pass s->data to C string interfaces.
2. Non-NULL input:
All the functions assume their input data pointer is non-NULL, unless otherwise documented, and may seg fault if passed NULL. The input data may *contain* null bytes, of course, just the data pointer itself must not be NULL.
Memory allocation
All the functions make a deep copy of all input data, and never store a pointer to the original input data.
