get information about file
.SH "LIBRARY"
libzip (-lzip)
.SH "SYNOPSIS"
#include <zip.h>
.PP
int
zip_stat(struct zip *archive, const char *fname, zip_flags_t flags, struct zip_stat *sb);
.PP
int
zip_stat_index(struct zip *archive, int index, zip_flags_t flags, struct zip_stat *sb);
.SH "DESCRIPTION"
The
zip_stat
function obtains information about the file named
\fBfname\fR
in
\fBarchive.\fR
The
\fBflags\fR
argument specifies how the name lookup should be done.
Its values are described in
zip_name_locate(3).
Also,
\fBZIP_FL_UNCHANGED\fR
may be
.I or'ed
to it to request information about the original file in the archive,
ignoring any changes made.
.PP
The
zip_stat_index
function obtains information about the file at position
\fBindex.\fR
.PP
The
\fBsb\fR
argument is a pointer to a
.PP
struct zip_stat
(shown below), into which information about the file is placed.
.Bd \-literal
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 */
};
.Ed
The structure pointed to by
\fBsb\fR
must be allocated before calling
zip_stat
or
zip_stat_index.
.PP
The
\fBvalid\fR
field of the structure specifies which other fields are valid.
Check if the flag defined by the following defines are in
\fBvalid\fR
before accessing the fields:

.SH "RETURN VALUES"
Upon successful completion 0 is returned.
Otherwise, \-1 is returned and the error information in
\fBarchive\fR
is set to indicate the error.
.SH "ERRORS"
The function
zip_stat
can fail for any of the errors specified for the routine
zip_name_locate(3).
.PP
The function
zip_stat_index
fails and sets the error information to
ZIP_ER_INVAL
if
\fBindex\fR
is invalid.
If
\fBZIP_FL_UNCHANGED\fR
is not set and no information can be obtained from the source
callback, the error information is set to
ZIP_ER_CHANGED.
