libzip: zip_stat(3)

NAME

zip_stat, zip_stat_index - get information about file

LIBRARY

libzip (-lzip)

SYNOPSIS

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 {
    const char *name;                   /* name of the file */
    int index;                          /* index within archive */
    unsigned int crc;                   /* crc of file data */
    unsigned int size;                  /* size of file (uncompressed) */
    time_t mtime;                       /* modification time */
    unsigned int comp_size;             /* size of file (compressed) */
    unsigned short comp_method;         /* compression method used */
    unsigned short encryption_method;   /* encryption method used */
};

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.
