Console I/O Routines 

Prototype 

char *getpass(const char *prompt); 

Description 

Reads a password. 

getpass reads a password from the system console after prompting with the null-terminated string prompt and disabling the echo. A pointer is returned to a null-terminated string of up to eight characters (not counting the null-terminator).

The return value is a pointer to a static string that is overwritten with each call. 

Example  

#include <conio.h>
 
int main(void)
{
   char *password;
 
   password = getpass("Input a password:");
   cprintf("The password is: %s\r\n", password);
   return 0;
}
