Gets a character from the keyboard.
Restriction: This function is supported for native COBOL only.
Syntax:
#include "cobscreen.h"
int cobgetch (void);
Equivalent COBOL Syntax:
call "CBL_READ_KBD_CHAR" using ...
Example:
The following code asks for a Yes/No response:
int ch;
cobaddstrc("Continue [y/n]? ");
ch = cobgetch();
if (ch == 'Y' || ch == 'y')
{
/* Yes */
Comments:
Reads a character from the keyboard and returns it. If no character is pending this routine waits until a key is pressed.
A value of -1 is returned on error (for example, EOF).
