C6273
Warning 6273 - non-integer passed as parameter <number> when integer is required in call to <function>: if a pointer value is being passed, %p should be used
This warning indicates that the format string specifies an integer, for example, a %d, length or precedence specification for printf but a non-integer such as a float, string, or struct is being passed as a parameter. This defect is likely to result in incorrect output.
Example
The following code generates this warning because an integer is required instead of a float to sprintffunction:
#include <stdio.h>
#include <string.h>
void f_defective()
{
char buff[50];
float f=1.5;
sprintf(buff, "%d",f);
}
The following code uses an integer cast to correct this warning:
#include <stdio.h>
#include <string.h>
void f_corrected()
{
char buff[50];
float f=1.5;
sprintf(buff,"%d",(int)f);
}
The following code uses safe string manipulation function, sprintf_s, to correct this warning:
#include <stdio.h>
#include <string.h>
void f_safe()
{
char buff[50];
float f=1.5;
sprintf_s(buff,50,"%d",(int)f);
}
This warning is not applicable on Windows 9x and Windows NT version 4 because %p is not supported on these platforms.
