* issues where we are being called from a project with a different default
|
|
* calling convention. For windows you have 3 define options:
|
|
* CJSON_HIDE_SYMBOLS - Define this in the case where you don't want to ever
|
|
* dllexport symbols
|
|
* CJSON_EXPORT_SYMBOLS - Define this on library build when you want to
|
|
* dllexport symbols (default)
|
|
* CJSON_IMPORT_SYMBOLS - Define this if you want to dllimport symbol
|
|
*
|
|
* For *nix builds that support visibility attribute, you can define similar
|
|
* behavior by setting default visibility to hidden by adding
|
|
* -fvisibility=hidden (for gcc)
|
|
* or
|
|
* -xldscope=hidden (for sun cc)
|
|
* to CFLAGS, then using the CJSON_API_VISIBILITY flag to "export" the same
|
|
* symbols the way CJSON_EXPORT_SYMBOLS does
