Question getchar()

hey everyone!
got another problem here.
how would i use the getchar() in a prompt:
Press any key to continue

the way i did it was to define a char variable named ch
and then wrote
Code:
char ch
...
ch = getchar();
printf("Press any key to continue");
getchar():

if you press enter it exits, but if you type anything else it displays it on the screen and you still have to press enter after.

is there anyway to make the program continue without displaying the result to the screen and so the user can press any key they want?

thanks
primal

PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME
getchar - get a byte from a stdin stream SYNOPSIS
#include <stdio.h> int getchar(void); DESCRIPTION
The getchar() function shall be equivalent to getc(stdin). RETURN VALUE
Refer to fgetc(). ERRORS
Refer to fgetc(). The following sections are informative. EXAMPLES
None. APPLICATION USAGE
If the integer value returned by getchar() is stored into a variable of type char and then compared against the integer constant EOF, the comparison may never succeed, because sign-extension of a variable of type char on widening to integer is implementation-defined. RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO
