zip_name_locate(3)

get index of file by name

NAME

zip_name_locate – get index of file by name

LIBRARY

libzip (-lzip)

SYNOPSIS

#include <zip.h>

zip_int64_t

zip_name_locate(zip_t *archive, const char *fname, zip_flags_t flags);

DESCRIPTION

The zip_name_locate() function returns the index of the file named fname in archive. If archive does not contain a file with that name, -1 is returned.

If neither ZIP_FL_ENC_RAW nor ZIP_FL_ENC_STRICT are specified, guess the encoding of the name in the ZIP archive and convert it to UTF-8, if necessary, before comparing.

If neither ZIP_FL_ENC_CP437 nor ZIP_FL_ENC_UTF_8 are specified, guess the encoding of fname.

Only CP-437 and UTF-8 are recognized.

The flags are specified by or'ing the following values, or 0 for none of them.

ZIP_FL_NOCASE

Ignore case distinctions. (Will only work well if the file names are ASCII.) With this flag, zip_name_locate() will be slow for archives with many files.

ZIP_FL_NODIR

Ignore directory part of file name in archive. With this flag, zip_name_locate() will be slow for archives with many files.

ZIP_FL_ENC_GUESS

This flag has no effect (its value is 0); it can be used to explicitly denote the absence of encoding flags.

ZIP_FL_ENC_RAW

Compare fname against the unmodified names as they are in the ZIP archive, without converting them to UTF-8.

ZIP_FL_ENC_STRICT

Follow the ZIP specification and expect CP-437 encoded names in the ZIP archive (except if they are explicitly marked as UTF-8). Convert them to UTF-8 before comparing.

ZIP_FL_ENC_CP437

fname is encoded as CP-437.

ZIP_FL_ENC_UTF_8

fname is encoded as UTF-8.

Note: ASCII is a subset of both CP-437 and UTF-8.

RETURN VALUES

zip_name_locate() returns the index of the file named fname or -1, if archive does not contain an entry of that name.

ERRORS

zip_name_locate() fails if:

[ZIP_ER_INVAL]

One of the arguments is invalid.

[ZIP_ER_MEMORY]

Required memory could not be allocated.

[ZIP_ER_NOENT]

No entry of the name fname is found in the archive.
