ZIP_STAT(3)						     Library Functions Manual						       ZIP_STAT(3)

NAME
zip_stat , - .Nm zip_stat_index get information about file LIBRARY
libzip (-lzip) SYNOPSIS
#include <zip.h> int zip_stat(struct zip *archive, const char *fname, int flags, struct zip_stat *sb); int zip_stat_index(struct zip *archive, int index, int flags, struct zip_stat *sb); DESCRIPTION
The zip_stat function obtains information about the file named fname in archive. The flags argument specifies how the name lookup should be done. Its values are described in zip_name_locate(3). Also, ZIP_FL_UNCHANGED may be or'ed to it to request information about the orig- inal file in the archive, ignoring any changes made. The zip_stat_index function obtains information about the file at position index. The sb argument is a pointer to a struct zip_stat (shown below), into which information about the file is placed. struct zip_stat { zip_uint64_t valid; /* which fields have valid values */ const char *name; /* name of the file */ zip_uint64_t index; /* index within archive */ zip_uint64_t size; /* size of file (uncompressed) */ zip_uint64_t comp_size; /* size of file (compressed) */ time_t mtime; /* modification time */ zip_uint32_t crc; /* crc of file data */ zip_uint16_t comp_method; /* compression method used */ zip_uint16_t encryption_method; /* encryption method used */ zip_uint32_t flags; /* reserved for future use */ }; The structure pointed to by sb must be allocated before calling zip_stat or zip_stat_index. The valid field of the structure specifies which other fields are valid. Check if the flag defined by the following defines are in valid before accessing the fields: ZIP_STAT_NAME name ZIP_STAT_INDEX index ZIP_STAT_SIZE size ZIP_STAT_COMP_SIZE comp_size ZIP_STAT_MTIME mtime ZIP_STAT_CRC crc ZIP_STAT_COMP_METHOD comp_method ZIP_STAT_ENCRYPTION_METHOD encryption_method ZIP_STAT_FLAGS flags RETURN VALUES
Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in archive is set to indicate the error. ERRORS
The function zip_stat can fail for any of the errors specified for the routine zip_name_locate(3). The function zip_stat_index fails and sets the error information to ZIP_ER_INVAL if index is invalid. If ZIP_FL_UNCHANGED is not set and no information can be obtained from the source callback, the error information is set to ZIP_ER_CHANGED. 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
