What is the equivalent to getch() & getche() in Linux?

Question

I am not able to find the equivalent header file for conio.h in Linux.

Is there any option for getch() & getche() function in Linux?

I want to make a switch case base menu where the user will give his option just by pressing one key & process should be moved ahead. I don't want to let user to press ENTER after pressing his choice.

#include <termios.h> #include <stdio.h>  static struct termios old, current;  /* Initialize new terminal i/o settings */ void initTermios(int echo)  {   tcgetattr(0, &old); /* grab old terminal i/o settings */   current = old; /* make new settings same as old settings */   current.c_lflag &= ~ICANON; /* disable buffered i/o */   if (echo) {       current.c_lflag |= ECHO; /* set echo mode */   } else {       current.c_lflag &= ~ECHO; /* set no echo mode */   }   tcsetattr(0, TCSANOW, &current); /* use these new terminal i/o settings now */ }  /* Restore old terminal i/o settings */ void resetTermios(void)  {   tcsetattr(0, TCSANOW, &old); }  /* Read 1 character - echo defines echo mode */ char getch_(int echo)  {   char ch;   initTermios(echo);   ch = getchar();   resetTermios();   return ch; }  /* Read 1 character without echo */ char getch(void)  {   return getch_(0); }  /* Read 1 character with echo */ char getche(void)  {   return getch_(1); }  /* Let's test it out */ int main(void) {   char c;   printf("(getche example) please type a letter: ");   c = getche();   printf("\nYou typed: %c\n", c);   printf("(getch example) please type a letter...");   c = getch();   printf("\nYou typed: %c\n", c);   return 0; } 

Output:

(getche example) please type a letter: g You typed: g (getch example) please type a letter... You typed: g
