Library

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
.
