Can't build a fuction that should return a structure

juanignaciotroi — Fri, 10 Jul 2015 15:32:22 GMT

Hello. I am developing using de FRDMKE02 and using the CW Sevelopment Studio. In my project, I have defined the following structure for dealing with time:

typedef struct TimeStruct {

unsigned char SECONDS;

unsigned char MINUTES;

unsigned char HOURS;

unsigned char DAY_OF_THE_WEEK;

unsigned char DATE;

unsigned char MONTH;

unsigned char YEAR;

};

I have done a fuction in which I want to add a determined quantity of time (days, hours and minutes; defined by char add_dd, char add_hh and char add_mm respectively) to the entrant TimeStruct and then it should return the resulting TimeStruct. The problem is that I can't even build this fuction.

The error log says that: "return type is an incomplete type".

I hope someone can help me. Regards, Juan Ignacio Troisi

The intended function is:

struct TimeStuct sumar_horas_y_minutos(struct TimeStruct TIEMPO_SUMADO,char add_dd,char add_hh,char add_mm){

TIEMPO_SUMADO.MINUTES = TIEMPO_SUMADO.MINUTES + add_mm;

if(TIEMPO_SUMADO.MINUTES > 59){

TIEMPO_SUMADO.HOURS ++;

TIEMPO_SUMADO.MINUTES = TIEMPO_SUMADO.MINUTES - 60;

}

TIEMPO_SUMADO.HOURS = TIEMPO_SUMADO.HOURS + add_hh;

if(TIEMPO_SUMADO.HOURS >= 24){

TIEMPO_SUMADO.DATE ++;

TIEMPO_SUMADO.HOURS = TIEMPO_SUMADO.HOURS - 24;

}

TIEMPO_SUMADO.DATE = TIEMPO_SUMADO.DATE + add_dd;

switch_month(TIEMPO_SUMADO);

if(TIEMPO_SUMADO.MONTH > 12){

TIEMPO_SUMADO.YEAR ++;

TIEMPO_SUMADO.MONTH = TIEMPO_SUMADO.MONTH -12;

}

return TIEMPO_SUMADO;

}

Hello Juan Ignacio Troisi:

There is a typo in your code:

That should be TimeStruct. Also for the typedef you should declare an identifier name.

Thank you but, unfortunately, I can't build build the project yet.

When I don't call the function, it builds. However, when I want to use it (it calling doing: 'sumar_horas_y_minutos(TIEMPO_SUMADO,add_dd,add_hh,add_mm);', the following error turns up:

"conflicting types for sumar_horas_y_minutos".

the code is:

struct TimeStruct sumar_horas_y_minutos(struct TimeStruct TIEMPO_SUMADO,char add_dd,char add_hh,char add_mm){
