zip_stat, zip_stat_index − get information about file
libzip (-lzip)
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
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
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.
