NAME

zip_stat, zip_stat_index - get information about file  

LIBRARY

libzip (-lzip)  

SYNOPSIS

#include <zip.h>

int
zip_stat(struct zip *archiveconst char *fnamezip_flags_t flagsstruct zip_stat *sb);

int
zip_stat_index(struct zip *archiveint indexzip_flags_t flagsstruct zip_stat *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.
