Hello, I'm trying to implement a code which copies a part of a string which is pointed to by a char (*outr_message), and adds it to an unsigned-char (UART1_error_format).
For example: if *outr_message is "e97" so UART1_error_format will be err97.
the current code is:
void Serial_Output_Full_Reset(char *outr_message) { unsigned char UART1_error_format[5] = "err"; //prepare the message set_message_in_transbuffer(String_Message, outr_message, NULL, NULL, 0, 0); #if __RS485__ if (&outr_message[1] == 'e') // converting 'eXX' to 'errXX' { strncpy(UART1_error_format, outr_message + 2, 2); UART1_error_format[5] = '\0'; random_write(0 ,0 , nooutr, UART1_error_format, 2); } #endif }
after compiling there's an error appearing:
new_meas_proc.c(52): warning C214: 'Argument': conversion: pointer to non-pointer
I've tried several ways to fix the warning, which is connected to the strncpy function I believe, since I've entered to the function 'random_write' correct variables types:
void random_write(float Treal, float Emiss, unsigned char Outr,unsigned char Err, unsigned char Scale);
What should be done to fix the warning? is a conversion from char to unsigned char also needed? Thanks much, Amitai pointers are quite confusing...
