ZIP_STAT(3) Library Functions Manual ZIP_STAT(3)


zip_stat, zip_stat_indexget information about file


libzip (-lzip)


#include <zip.h>

zip_stat(zip_t *archive, const char *fname, zip_flags_t flags, zip_stat_t *sb);

zip_stat_index(zip_t *archive, zip_uint64_t index, zip_flags_t flags, zip_stat_t *sb);


The () 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 'ed to it to request information about the original file in the archive, ignoring any changes made.

The () 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 () 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.
