Replace all occurences of unsigned int and unsigned long with size_t.
This is a backwards incompatible change, as the signature of many API
functions changes.
Returns a new JSON array, or *NULL* on error. Initially, the array
is empty.
-.. cfunction:: unsigned int json_array_size(const json_t *array)
+.. cfunction:: size_t json_array_size(const json_t *array)
Returns the number of elements in *array*, or 0 if *array* is NULL
or not a JSON array.
-.. cfunction:: json_t *json_array_get(const json_t *array, unsigned int index)
+.. cfunction:: json_t *json_array_get(const json_t *array, size_t index)
.. refcounting:: borrow
if *array* is *NULL*, or if *index* is out of range, *NULL* is
returned.
-.. cfunction:: int json_array_set(json_t *array, unsigned int index, json_t *value)
+.. cfunction:: int json_array_set(json_t *array, size_t index, json_t *value)
Replaces the element in *array* at position *index* with *value*.
The valid range for *index* is from 0 to the return value of
:cfunc:`json_array_size()` minus 1. Returns 0 on success and -1 on
error.
-.. cfunction:: int json_array_set_new(json_t *array, unsigned int index, json_t *value)
+.. cfunction:: int json_array_set_new(json_t *array, size_t index, json_t *value)
Like :cfunc:`json_array_set()` but steals the reference to *value*.
This is useful when *value* is newly created and not used after
.. versionadded:: 1.1
-.. cfunction:: int json_array_insert(json_t *array, unsigned int index, json_t *value)
+.. cfunction:: int json_array_insert(json_t *array, size_t index, json_t *value)
Inserts *value* to *array* at position *index*, shifting the
elements at *index* and after it one position towards the end of
.. versionadded:: 1.1
-.. cfunction:: int json_array_insert_new(json_t *array, unsigned int index, json_t *value)
+.. cfunction:: int json_array_insert_new(json_t *array, size_t index, json_t *value)
Like :cfunc:`json_array_insert()` but steals the reference to
*value*. This is useful when *value* is newly created and not used
.. versionadded:: 1.1
-.. cfunction:: int json_array_remove(json_t *array, unsigned int index)
+.. cfunction:: int json_array_remove(json_t *array, size_t index)
Removes the element in *array* at position *index*, shifting the
elements after *index* one position towards the start of the array.
Returns a new JSON object, or *NULL* on error. Initially, the
object is empty.
-.. cfunction:: unsigned int json_object_size(const json_t *object)
+.. cfunction:: size_t json_object_size(const json_t *object)
Returns the number of elements in *object*, or 0 if *object* is not
a JSON object.
The following functions perform the actual JSON encoding. The result
is in UTF-8.
-.. cfunction:: char *json_dumps(const json_t *root, unsigned long flags)
+.. cfunction:: char *json_dumps(const json_t *root, size_t flags)
Returns the JSON representation of *root* as a string, or *NULL* on
error. *flags* is described above. The return value must be freed
by the caller using :cfunc:`free()`.
-.. cfunction:: int json_dumpf(const json_t *root, FILE *output, unsigned long flags)
+.. cfunction:: int json_dumpf(const json_t *root, FILE *output, size_t flags)
Write the JSON representation of *root* to the stream *output*.
*flags* is described above. Returns 0 on success and -1 on error.
*output*. In this case, the output is undefined and most likely not
valid JSON.
-.. cfunction:: int json_dump_file(const json_t *json, const char *path, unsigned long flags)
+.. cfunction:: int json_dump_file(const json_t *json, const char *path, size_t flags)
Write the JSON representation of *root* to the file *path*. If
*path* already exists, it is overwritten. *flags* is described
