Hello everybody,
First of all I thank you all. With the help of you people I have started programming in C. I have completed my first project in C.
Now in my another project, I used the atoi function. I am getting warning & an error like-
MAIN.C(255): warning C206: 'atoi': missing function-prototype MAIN.C(255): error C267: 'atoi': requires ANSI-style prototype
If I use the function without any argument, I get no errors. I have included the function prototypes, some of my code is as..
void data_rcvd_proc() { char *recd_cmd; // command part of the string unsigned char *recd_dat; // data part of the string unsigned char idata tmp_data[17]; ES=0; // disable serial interrupt /* SET DATA */ if (strpos (RxBuffer, '=') != -1){ // if '=' found recd_cmd = strtok(RxBuffer,"="); recd_dat = strtok(NULL,"+"); if(strcmp(recd_cmd, "DELAY_TIME")==0){ // delay_time = atoi(recd_dat); //atoi converts ascii number string into integer } else if(strcmp(recd_cmd, "UP")==0){ // up_time = atoi(recd_dat); //atoi converts ascii number string into integer } else if(strcmp(recd_cmd, "Down")==0){ up_time = atoi(); //atoi converts ascii number string into integer } } }
Pleas help! I cannot understand the problem because in my previous project I HAD EXACTLY USED THE SAME WAY & IT WAS WORKING PERFECTLY , Thanks.
Thanks Per, everything is clear to me know. I had not included the stdlib.h file anywhere in my previous project, but I had declared the atoi function in my file.
void init_all(); //initialise all things unsigned char segs2ascii(unsigned char); void read_rtc(); void write_rtc(); char kbhit(); void gps_rcvd_proc(); void data_rcvd_proc(); int atoi(char *string); /* string to convert */ void read_eeprom(); void write_eeprom(); void erase_eeprom(); void SER_init(); void beep(ms);
Thanks again
Don't do that. Always use the standard header files when using standard functions.
Ok Per, actually it was done in my older project. I had seen that way somewhere.
But now I have included stdlib.h file itself.
