using fopen getting a lot of warnings

netiad · 04-28-2007, 07:28 PM

Hello,

When I compile the below I get 2 warnings.... warning: deprecated conversion from string constant to char*

How can I make this warning go away? I am using a lot of compile time warning flags by the way.

Code:

#include <stdio.h>
#include <stdlib.h>

void file_write (char file_path[], char text_to_write[]);

int main(){
	
	file_write  ("C:\\windows\\temp\\lala.txt", "Written by John");
	
	return 0;
}

void file_write (char file_path[], char text_to_write[]){
	FILE *file;
	
	file = fopen(file_path, "wt");
	fprintf (file, "%s", text_to_write);
	fclose (file);
}

thanks.

Other than using a non-microsoft compiler, read the warning text as it should tell you exactly how to make it go away(a preprocessor definition, _CRT_SECURE_NO_DEPRECATE, probably). The warning can alternatively be ignored, unless you want to use one of microsoft's 'safe' alternatives.
