ZIP_SOURCE(5) File Formats Manual ZIP_SOURCE(5) NAME zip_source -- zip data source structure LIBRARY libzip (-lzip) SYNOPSIS #include <zip.h> zip_source_t *source; DESCRIPTION A zip_source_t represents a data source (or destination when used for writing). libzip(3) uses it for adding or replacing file contents for a file in a zip archive. If the source supports seeking, it can also be used to open zip archives from. Data can come from a file on disk (zip_source_file(3), zip_source_file_create(3), zip_source_filep(3), or zip_source_filep_create(3)), memory (zip_source_buffer(3), zip_source_buffer_create(3), zip_source_buffer_fragment(3), or zip_source_buffer_fragment_create(3)), a file inside an archive (zip_source_zip(3)), or provided via a callback function (zip_source_function(3) or zip_source_function_create(3)). zip_source_window(3) or zip_source_window_create(3) can be used re- strict access to a part of the contained data. It can also be used as a filter to process the data provided by an un- derlying zip_source_t (e.g., to compress it or compute a checksum), created with zip_source_layered(3) or zip_source_layered_create(3)). Sources are freed with zip_source_free(3). Sources must support reading, and can optionally support seeking and writing. zip_source_t is reference counted, and created with a reference count of 1. zip_open_from_source(3), zip_file_add(3), and zip_file_replace(3) will take ownership of the passed source (decrement the reference count when they are done using it), so zip_source_free(3) only needs to be called when these functions return an error. The un- derlying data (file or buffer) must remain valid until the archive is closed. Use zip_source_keep(3) to increase the reference count, for example if you need the source after zip_close(3).
