C6063
warning C6063: missing string argument to <function> corresponding to conversion specifier <number>
This warning indicates that not enough arguments are being provided to match a format string; at least one of the missing arguments is a string. This defect can cause crashes and buffer overflows (if the called function is of the sprintf family), as well as potentially incorrect output.
Example
The following code generates this warning:
#include <string.h>
void f( )
{
char buff[15];
sprintf(buff, "%s %s", "Hello, World!");
}
To correct this warning, provide additional arguments as shown in the following code:
#include <string.h>
void f( )
{
char buff[15];
sprintf(buff, "%s %s ", "Hello","World");
}
The following code corrects this warning using safe string manipulation function:
#include <string.h>
void f( )
{
char buff[15];
sprintf_s( buff, sizeof(buff),"%s", "Hello, World!" );
}
