I try to send a 32 bits uint32_t value from LUA to C (ie in fact a 0xRRGGBBAA pattern) and i am facing the following issue :
  • If i do a 0xFF0000FF -> I get the value 0x80000000 with luaL_checkinteger()
  • If i do not set the MSB (ie 0x7F0000FF for example) -> I get the correct value  with luaL_checkinteger()
I guess it has something to do with sign conversion, but i do not know if it is a bug or a normal behavior with luaJIT.

Any hint or idea ?

Best rgds,
