SYNOPSIS


.In 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 int 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.
