Basic Usage Example
Here’s a simple example to illustrate the creation of a ZIP file using LibZIP:
#include <zip.h> int main() { int errorp = 0; zip_t *zip = zip_open("example.zip", ZIP_CREATE | ZIP_TRUNCATE, &errorp); if (!zip) { fprintf(stderr, "Error creating zip file: %d ", errorp); return 1; } const char *content = "Hello, LibZIP!"; zip_source_t *source = zip_source_buffer(zip, content, strlen(content), 0); zip_file_add(zip, "hello.txt", source, ZIP_FL_OVERWRITE); zip_close(zip); return 0; } In this example, a new ZIP file named example.zip is created, containing a single file hello.txt with a simple text message.
Advanced Features
Compression Levels
LibZIP offers multiple compression levels, letting developers balance between speed and size. By specifying the compression level when adding files to a ZIP archive, you can control the trade-off according to your application’s requirements.
Error Handling
Proper error handling is a critical aspect of robust software development. LibZIP provides extensive error codes and functions that allow developers to gracefully handle exceptions and errors during ZIP file operations.
