Scenario: I have an array with "n" elements and I wish to pass these n elements as arguments to some function that accepts variable number of arguments.
I am actually trying to write a log function which given an input string and variables, logs them onto a file (STDOUT, say).
Following is the python equivalent of what I want to achieve:
def log(time, num, *arg):
print(time, *arg)
return
log("19:00", 2, 3, "abc")
Following is my attempt to do the same in C
#include <stdarg.h>
#include <stdio.h>
void log(const char* time, int num, ...)
{
// num is the number of arguments
va_list valist;
va_start(valist, num);
// what do i do next?
}
int main()
{
log("19:00", 2, 3, "abc");
}
Output should be:
19:00 3 abc
It would be better if someone can suggest a method in which I could simply pass formatted string and arguments to log function in C like:
int d = 3;
char s[4] = "abc\0";
log("%s %d %s", "19:00", d, s);
