c++ - How do I use FRESetContextNativeData() in AIR native extensions? -

i'm building ane. in 1 of calls native code, there's object gets created, , i'd able keep in memory reference in future call.

i thought could creating pointer object, , passing pointer fresetcontextnativedata() in example below:

freobject storedata(frecontext ctx, void* funcdata, uint32_t argc, freobject argv[]) {     char* data = "testing...";     fresetcontextnativedata( ctx, &data );     return getfrestring(data); }  freobject retrievedata(frecontext ctx, void* funcdata, uint32_t argc, freobject argv[]) {     char* data;     fregetcontextnativedata(ctx, (void**)&data);     return getfrestring(data); } 

this doesn't seem work however. @ end of retrievedata(), data points bunch of randomness. gives?

so i'm bit of idiot. mistake made putting & before data in call fresetcontextnativedata(). 1 needs pointer, not pointer pointer fregetcontextnativedata().

the following code produces results expecting:

freobject storedata(frecontext ctx, void* funcdata, uint32_t argc, freobject argv[]) {     char* data = "testing..."     fresetcontextnativedata( ctx, (void*)data );     return getfrestring(data); }  freobject retrievedata(frecontext ctx, void* funcdata, uint32_t argc, freobject argv[]) {     char *data;     fregetcontextnativedata(ctx, (void**)&data);     return getfrestring(data); }
