zip_name_locate - Man Page
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.
