NAME
zip_add , - .Nm zip_replace add file to zip archive or replace file in zip archive LIBRARY
libzip (-lzip) SYNOPSIS
#include <zip.h> zip_int64_t zip_add(struct zip *archive, const char *name); "struct zip_source *source" int zip_replace(struct zip *archive, zip_uint64_t index); "struct zip_source *source" DESCRIPTION
The function zip_add adds a file to a zip archive, while zip_replace replaces an existing file in a zip archive. The argument archive specifies the zip archive to which the file should be added. name is the file's name in the zip archive (for zip_add ), while index speci- fies which file should be replaced (for zip_replace ). The data is obtained from the source argument. See the zip_source_* functions cited in SEE ALSO. RETURN VALUES
Upon successful completion, zip_add returns the index of the new file in the archive, and zip_replace returns 0. Otherwise, -1 is returned and the error code in archive is set to indicate the error. EXAMPLES
struct zip_source *s; if ((s=zip_source_buffer(archive, buffer, len)) == NULL || zip_add(archive, name, s) 0) { zip_source_free(s); printf("error adding file: %s0, zip_strerror(archive)); } ERRORS
zip_add and zip_replace fail if: [ZIP_ER_EXISTS] There is already a file called name in the archive. (Only applies to zip_add ). [ZIP_ER_INVAL] source or name are NULL, or index is invalid. [ZIP_ER_MEMORY] Required memory could not be allocated. SEE ALSO

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. SEE ALSO
