ZIP_STAT(3) Library Functions Manual ZIP_STAT(3)

zip_stat, zip_stat_index
get information about file

libzip (-lzip)

#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);

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:

Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in archive is set to indicate the error.

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.

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.
