zip_open, zip_open_from_source —
open zip archive
libzip (-lzip)
#include <zip.h>
zip_t *
zip_open(const char *path, int flags, int *errorp);
zip_t *
zip_open_from_source(zip_source_t *zs, int flags, zip_error_t *ze);
The zip_open() function opens the zip archive specified by path and returns a pointer to a struct zip, used to manipulate the archive. The flags are specified by or'ing the following values, or 0 for none of them.
ZIP_CHECKCONSPerform additional stricter consistency checks on the archive, and error if they fail.ZIP_CREATECreate the archive if it does not exist.ZIP_EXCLError if archive already exists.ZIP_TRUNCATEIf archive exists, ignore its current contents. In other words, handle it the same way as an empty archive.ZIP_RDONLYOpen archive in read-only mode.
If an error occurs and errorp is non-NULL, it will be set to the corresponding error code.
The zip_open_from_source() function opens a zip archive encapsulated by the zip_source zs using the provided flags. In case of error, the zip_error ze is filled in.
Upon successful completion zip_open() and zip_open_from_source() return a struct zip pointer. Otherwise, NULL is returned and zip_open() sets *errorp to indicate the error, while zip_open_from(source) sets ze to indicate the error.
The archive specified by path is opened unless:[ZIP_ER_EXISTS]The file specified by path exists and ZIP_EXCL is set.[ZIP_ER_INCONS]Inconsistencies were found in the file specified by path. This error is often caused by specifying ZIP_CHECKCONS but can also happen without it.[ZIP_ER_INVAL]The path argument is NULL.[ZIP_ER_MEMORY]Required memory could not be allocated.[ZIP_ER_NOENT]The file specified by path does not exist and ZIP_CREATE is not set.[ZIP_ER_NOZIP]The file specified by path is not a zip archive.[ZIP_ER_OPEN]The file specified by path could not be opened.[ZIP_ER_READ]A read error occurred; see errno for details.[ZIP_ER_SEEK]The file specified by path does not allow seeks.
libzip(3), zip_close(3), zip_error_strerror(3), zip_fdopen(3)
zip_open() and zip_open_from_source() were added in libzip 1.0.
