+Synopsis

+.. c:function:: #include <sds.h>
+
+.. c:function:: sds sdsnew(const char *init)
+ sds sdsnewlen(const void *init, size_t initlen)
+
+
+Description
+-----------
+
+The function :c:func:`sdsnew()` creates an SDS string from a C null terminated string.
+
+The function :c:func:`sdsnewlen()` is similar to :c:func:`sdsnew()` but
+instead of creating the string assuming that the input string is null
+terminated, it gets an additional length parameter. This way you can create a
+string from binary data.
+
+Return value
+------------
+
+Upon successful completion, these functions will allocate and return a new SDS
+string. If the allocation fails they will return :c:data:`NULL`.
