ZIP_SOURCE_ZIP(3) BSD Library Functions Manual ZIP_SOURCE_ZIP(3) NAME zip_source_zip -- create data source from zip file LIBRARY libzip (-lzip) SYNOPSIS #include <zip.h> zip_source_t * zip_source_zip(zip_t *archive, zip_t *srcarchive, zip_uint64_t srcidx, zip_flags_t flags, zip_uint64_t start, zip_int64_t len); DESCRIPTION The function zip_source_zip() creates a zip source from a file in a zip archive. The srcarchive argument is the (open) zip archive containing the source zip file at index srcidx. len bytes from offset start will be used in the zip_source. If len is 0 or -1, the rest of the file, start- ing from start, is used. If start is zero and len is -1, the whole file will be copied without decompressing it. Supported flags are: ZIP_FL_UNCHANGED Try to get the original data without any changes that may have been made to srcarchive after open- ing it. ZIP_FL_RECOMPRESS When adding the data from srcarchive, re-compress it using the current settings instead of copying the compressed data. RETURN VALUES Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error. ERRORS zip_source_zip() fails if: [ZIP_ER_CHANGED] Unchanged data was requested, but it is not available. [ZIP_ER_INVAL] srcarchive, srcidx, start, or len 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().
