We are running a survey to help us improve the experience for all of our members. If you see the survey appear, please take the time to tell us about your experience if you can.
please explain me why the sizeof (C51) returns 6 bytes for this struct instead of 5:
typedef struct DEKO_COMM_HEADER { UINT16 m_uiMsgOpcode; UCHAR8 m_sblMsgPriority :2; UINT16 m_sblDataLength :11; UINT16 m_sblMsgTimeStamp :11; }DEKO_COMM_HEADER, *PDEKO_COMM_HEADER;
UINT16 is typedef for unsigned int UCHAR8 is typedef for unsigned char
thanks
"it is undefineded in c standard "
To be precise, the 'C' standard states that it is Implementation-Defined - this means that the implementation can choose to do whatever it likes, but this must be documented.
