ZIP_SOURCE_ZIP(3) Library Functions Manual ZIP_SOURCE_ZIP(3)
NAME
zip_source_zip - create data source from zip file
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
struct zip_source * zip_source_zip(struct zip *archive, struct zip *srcarchive); "zip_uint64_t srcidx" "int 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 contain-
ing 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, starting 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 opening it.
ZIP_FL_RECOMPRESS When adding the data from srcarchive, re-compress it using the current settings instead of copying the com-
pressed 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.
