// ctrlv.c - Simulates pressing Ctrl-V once a second

// To compile with MinGW:
//
//      gcc -o ctrlv.exe ctrlv.c
//
// To run the program:
//
//      ctrlv.exe
//

// Because the SendInput function is only supported in
// Windows 2000 and later, WINVER needs to be set as
// follows so that SendInput gets defined when windows.h
// is included below.
#define WINVER 0x0500
#include <windows.h>
