ZIP_STAT(3)

NAME
zip_stat , - .Nm zip_stat_index get information about file

LIBRARY
libzip (-lzip)

SYNOPSIS
#include <zip.h>

int zip_stat(struct zip *archive, const char *fname, int flags, struct zip_stat *sb);

int zip_stat_index(struct zip *archive, int index, int flags, struct 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.
