How to get last one hour mail using c

To retrieve the last one hour's emails using C, you'll need to use a library that interacts with your email provider's API or a library that provides a way to access your email account. Here are a few options:

Option 1: Using IMAP (Internet Message Access Protocol)

IMAP is a protocol that allows you to access your email account remotely. You can use the imap library in C to connect to your email provider's IMAP server and retrieve the last one hour's emails.

Here's an example using the imap library:

#include <imap.h>
#include <stdio.h>
#include <time.h>

int main() {
    // Set up IMAP connection
    imap_t *imap = imap_open("imap.gmail.com", "[email protected]", "your_password");
    if (!imap) {
        printf("Error connecting to IMAP server\n");
        return 1;
    }

    // Set the search criteria to retrieve emails from the last hour
    imap_search_t *search = imap_search(imap, "SINCE 1 hour ago");
    if (!search) {
        printf("Error searching for emails\n");
        return 1;
    }

    // Loop through the search results and print the emails
    imap_msg_t *msg;
    while ((msg = imap_msg(imap, search))) {
        printf("Subject: %s\n", imap_msg_subject(msg));
        printf("From: %s\n", imap_msg_from(msg));
        printf("Date: %s\n", imap_msg_date(msg));
        printf("\n");
    }

    // Clean up
    imap_close(imap);
    return 0;
}

Option 2: Using POP3 (Post Office Protocol version 3)

POP3 is another protocol that allows you to access your email account remotely. You can use the pop3 library in C to connect to your email provider's POP3 server and retrieve the last one hour's emails.

Here's an example using the pop3 library:

#include <pop3.h>
#include <stdio.h>
#include <time.h>

int main() {
    // Set up POP3 connection
    pop3_t *pop3 = pop3_open("pop.gmail.com", "[email protected]", "your_password");
    if (!pop3) {
        printf("Error connecting to POP3 server\n");
        return 1;
    }

    // Set the search criteria to retrieve emails from the last hour
    pop3_search_t *search = pop3_search(pop3, "SINCE 1 hour ago");
    if (!search) {
        printf("Error searching for emails\n");
        return 1;
    }

    // Loop through the search results and print the emails
    pop3_msg_t *msg;
    while ((msg = pop3_msg(pop3, search))) {
        printf("Subject: %s\n", pop3_msg_subject(msg));
        printf("From: %s\n", pop3_msg_from(msg));
        printf("Date: %s\n", pop3_msg_date(msg));
        printf("\n");
    }

    // Clean up
    pop3_close(pop3);
    return 0;
}

Option 3: Using a library that provides a way to access your email account

There are several libraries available that provide a way to access your email account, such as libcurl or libmail. These libraries often provide a higher-level interface for interacting with your email account, making it easier to retrieve the last one hour's emails.

For example, using libcurl:

#include <curl/curl.h>
#include <stdio.h>
#include <time.h>

int main() {
    // Set up curl
    CURL *curl;
    CURLcode res;
    curl_global_init(CURL_GLOBAL_DEFAULT);
    curl = curl_easy_init();
    if (!curl) {
        printf("Error initializing curl\n");
        return 1;
    }

    // Set the URL for the email account
    curl_easy_setopt(curl, CURLOPT_URL, "https://imap.gmail.com");

    // Set the search criteria to retrieve emails from the last hour
    curl_easy_setopt(curl, CURLOPT_POST, 1L);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "search=SINCE 1 hour ago");

    // Loop through the search results and print the emails
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_email);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &email);

    // Perform the request
    res = curl_easy_perform(curl);
    if (res!= CURLE_OK) {
        printf("Error retrieving emails\n");
        return 1;
    }

    // Clean up
    curl_easy_cleanup(curl);
    return 0;
}

static size_t write_email(void *ptr, size_t size, size_t nmemb, void *data) {
    email_t *email = (email_t *)data;
    email->subject = (char *)ptr;
    return size * nmemb;
}

Note that these examples are just a starting point, and you'll need to modify them to fit your specific use case. Additionally, you may need to handle errors and exceptions more robustly.
