curs_scanw - Linux
Overview
curs_scanw is a curses library function that reads input from the user and scans it according to a specified format string. It is typically used to read user input for curses applications, allowing for sophisticated and user-friendly text-based interfaces.
Syntax
int curs_scanw(const char *fmt, ...);
Options/Flags
None.
Examples
Example 1: Reading a Single Character
int ch;
curs_scanw("%c", &ch);
Example 2: Reading a String
char name[50];
curs_scanw("%s", name);
Example 3: Reading an Integer and a Float
int age;
float weight;
curs_scanw("%d %f", &age, &weight);
Common Issues
- Incorrect format strings: Ensure that the format string matches the expected input.
- Buffer overflow: Allocate sufficient space for the input data to avoid memory issues.
Integration
curs_scanw can be integrated with other curses functions to create complex user interfaces. For example:
void get_user_input() {
char input[50];
curs_scanw("%s", input);
process_input(input);
}
