* Use "printf" instead of "echo -n" as it's more portable
* Treat a test as skipped if it exits with exit status of 77
* Skip the check_exports test if "nm -D" doesn't work
Thanks to Basile Starynkevitch for the suggestion and initial patch.
Thanks to Jonathan Landis and Deron Meranda for showing how this can
be utilized for implementing secure memory operations.
Expand the pack/unpack API: json_(un)pack is the simple version with
no error output, json_(un)pack_ex has error output and flags,
json_v(un)pack_ex is a va_list version of json_(un)pack_ex.
Implement unpacking flags:
- JSON_UNPACK_ONLY turns off extra validation, i.e. array and object
unpacking doesn't check that all items are unpacked. This is really
just convenience for not adding '*' after each object and array.
- JSON_VALIDATE_ONLY turns off unpacking, i.e. no varargs are expected
and nothing is unpacked.
After looking at the new code for a few days, I didn't like it
anymore. To prepare for the future, a few fields will be added to the
json_error_t struct later.
This reverts commit 23dd078c8d. Some
adjustments were needed because of newer commits.
All decoding functions now accept a json_error_t** parameter and set
it to point to a heap-allocated json_error_t structure if an error
occurs. The contents of json_error_t are no longer exposed directly, a
few functions to do it have been added instead. If an error occurs,
the user must free the json_error_t value.
This makes it possible to enhance the error reporting facilities in
the future without breaking ABI compatibility with older versions.
This is a backwards incompatible change.
