Don't get input from user after getch()

[Hamad mahmood]

I'm doing something like given below

#include <stdio.h>
#include <ncurses.h>

int main()
{
int ch;
ch = getch();
while( ch != 'E' )
{
if( ch == 65 )
{
char buf[50];
getline( (char **) buf, (int *) 50, stdin);
printw("%s", buff);
}
ch = getch();
}
return 0;
}

getline get failed after getch(), don't know waht is happening.

the compiler was gentle enough to tell you that your usage of the function was incorrect, don't cast away error messages.

man getline wrote:

getline() reads an entire line from stream, storing the address of the buffer
containing the text into *lineptr. The buffer is null-terminated and includes
the newline character, if one was found.

If *lineptr is set to NULL and *n is set 0 before the call, then getline() will
allocate a buffer for storing the line. This buffer should be freed by the
user program even if getline() failed.

Alternatively, before calling getline(), *lineptr can contain a pointer to a
malloc-allocated buffer *n bytes in size.

Either you provide a dynamic allocated string, or you left the fuction allocate it for you.


By the way, getline() is from stdio, I don't think that you can mix it with ncurses so freely.
