时间: 2024-05-19 13:14:32 浏览: 9
This warning message indicates that the function prototype for the function "vDevice_Ctrl" is missing. A function prototype is a declaration of the function that specifies the function name, return type, and parameter types.
To resolve this warning, you should provide a function prototype for "vDevice_Ctrl" before it is used in the main function. The function prototype should match the actual function definition in terms of the function name, return type, and parameter types.
For example, if the "vDevice_Ctrl" function is defined as follows:
void vDevice_Ctrl(int arg1, float arg2);
Then the function prototype should be declared before the main function as follows:
void vDevice_Ctrl(int arg1, float arg2);
int main()
{
// code that uses vDevice_Ctrl function
// ...
return 0;
}
