ZIP_STAT(3) BSD 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(zip_t *archive, const char *fname, zip_flags_t flags, zip_stat_t *sb);

int

zip_stat_index(zip_t *archive, zip_uint64_t index, zip_flags_t flags, zip_stat_t *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.

HISTORY

zip_stat() was added in libzip 0.6. In libzip 0.11 the type of flags was changed from int to zip_flags_t.

zip_stat_index() was added in libzip 0.6. In libzip 0.10 the type of index was changed from int to zip_uint64_t. In libzip 0.11 the type of flags was changed from int to zip_flags_t.
