ZIP_SOURCE_ZIP_FILE(3) Library Functions Manual ZIP_SOURCE_ZIP_FILE(3) NAME zip_source_zip_file, zip_source_zip_file_create -- create data source from zip file LIBRARY libzip (-lzip) SYNOPSIS #include <zip.h> zip_source_t * zip_source_zip_file(zip_t *archive, zip_t *srcarchive, zip_uint64_t srcidx, zip_flags_t flags, zip_uint64_t start, zip_int64_t length, const char *password); zip_source_t * zip_source_zip_file_create(zip_t *srcarchive, zip_uint64_t srcidx, zip_flags_t flags, zip_uint64_t start, zip_int64_t length, const char *password, zip_error_t *error); DESCRIPTION The functions zip_source_zip_file() and zip_source_zip_file_create() create a zip source from a file in a zip archive. The srcarchive argu- ment is the (open) zip archive containing the source zip file at index srcidx. length bytes from offset start will be used in the zip_source. If length is -1, the rest of the file, starting from start, is used. If you intend to copy a file from one archive to another, using the flag ZIP_FL_COMPRESSED is more efficient, as it avoids recompressing the file data. Supported flags are: ZIP_FL_COMPRESSED Get the compressed data. This is only supported if the complete file data is requested (start == 0 and length == -1). This is not supported for changed data. Default is uncompressed. ZIP_FL_ENCRYPTED Get the encrypted data. (This flag implies ZIP_FL_COMPRESSED.) This is only supported if the complete file data is requested (start == 0 and length == -1). Default is decrypted. ZIP_FL_UNCHANGED Try to get the original data without any changes that may have been made to srcarchive after open- ing it. RETURN VALUES Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive or error is set to indi- cate the error. ERRORS zip_source_zip_file() and zip_source_zip_file_create() fail if: [ZIP_ER_CHANGED] Unchanged data was requested, but it is not avail- able. [ZIP_ER_INVAL] srcarchive, srcidx, start, or length are invalid. [ZIP_ER_MEMORY] Required memory could not be allocated. Additionally, it can return all error codes from zip_stat_index() and zip_fopen_index().
