Windows Development API Reference

Overview

This document provides a comprehensive overview of the Windows Development API.

The Windows Development API is a set of APIs that allows developers to interact with the Windows operating system.

Core Components

We'll cover a few core components:

Key Functions

Here are a few important functions:

  • `CreateFileW()`: Creates a file handle.
  • `CloseHandle()`: Closes a file handle.
  • `CreateFile()`: Creates a file.
  • `ReadFile()`: Reads data from a file.
  • `WriteFile()`: Writes data to a file.
  • `GetFileTime()`: Retrieves the current time.
  • `SetFileTime()`: Sets the current time.

Example - Simple Read File

Here's a simple example demonstrating reading data from a file:


        #include 

        int main() {
            FILE *fp;
            char filename[100];

            fp = fopen(filename, "r");
            if (fp == NULL) {
                perror("Error opening file");
                return 1;
            }

            char buffer[256];
            if (fgets(buffer, 256, fp) != NULL) {
                printf("File contents:\n%s", buffer);
            }

            fclose(fp);
            return 0;
        }

This code reads the first 256 characters from the file specified by `filename`.
