input-with-timeout

This project includes a function in the C programming language that receives user input with a timeout.

Usage

To run this code, first compile it:

gcc main.c -o main

Functions

char* remove_last_character(char* str): This function removes the last character of a string.
char* add_character_to_end(char* str, char character): This function adds a character to the end of a string.
char* input_with_timeout(const char* prompt, const unsigned int timeout): This function receives user input with a timeout.

Note for Memory Management

After using the pointer returned by the function input_with_timeout, make sure to free the allocated memory using free() to avoid memory leaks !

Alerts

Note

This code includes functions that manipulate strings in C. It's important to understand how memory allocation works in C before using these functions.

Warning

This code uses the malloc function to allocate memory and the free function to deallocate memory. Always ensure that you have freed any memory that you have allocated to prevent memory leaks.

Tip

The input_with_timeout function allows you to set a timeout for user input. This can be useful in scenarios where your program needs to continue executing if the user does not provide input within a certain timeframe.

Important

The remove_last_character and add_character_to_end functions modify the original string. If you need to keep the original string unchanged, make sure to create a copy of the string before using these functions.

Example

char *input = input_with_timeout("Enter your input: ", 20);

if (input != NULL) {
    printf("Input received: '%s'.\n", input);
    free(input);
} else {
    printf("Timeout occurred. Returning NULL.\n");
}
