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.
