libzip (-lzip)SYNOPSIS
#include <zip.h>struct zip_file * zip_fopen(struct zip *archive, const char *fname, int flags);
struct zip_file * zip_fopen_index(struct zip *archive, zip_uint64_t index, int flags);
DESCRIPTION
The zip_fopen function opens the file name fname in archive. The flags argument specifies how the name lookup should be done, according to the values are described in zip_name_locate(3). Also, the following values may be or'ed to it.-
- ZIP_FL_COMPRESSED
- Read the compressed data. Otherwise the data is uncompressed by zip_fread.
- ZIP_FL_UNCHANGED
- Read the original data from the zip archive, ignoring any changes made to the file.
The zip_fopen_index function opens the file at position index.
If encrypted data is encountered, the functions call zip_fopen_encrypted(3) or zip_fopen_index_encrypted(3) respectively, using the default password set with zip_set_default_password(3).
