ZIP_STAT(3) Library Functions Manual ZIP_STAT(3)NAME
zip_stat, zip_stat_index - get information about file
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
int
zip_stat(struct zip *archive, const char *fname, zip_flags_t
flags, struct zip_stat *sb);
int
zip_stat_index(struct zip *archive, int index, zip_flags_t
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
original 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.
