get name of file by index

libzip (-lzip)

#include <zip.h>

const char *
zip_get_name(zip_t *archive, zip_uint64_t index, zip_flags_t flags);

The zip_get_name() function returns the name of the file at position index in archive. The name is in UTF-8 encoding unless ZIP_FL_ENC_RAW was specified (see below).

If flags is set to ZIP_FL_UNCHANGED, the original unchanged filename is returned. The returned string must not be modified or freed, and becomes invalid when archive is closed.

Additionally, the following flags are supported:

Return the unmodified names as it is in the ZIP archive.
(Default.) Guess the encoding of the name in the ZIP archive and convert it to UTF-8, if necessary. (Only CP-437 and UTF-8 are recognized.)
Follow the ZIP specification and expect CP-437 encoded names in the ZIP archive (except if they are explicitly marked as UTF-8). Convert it to UTF-8.
Note: ASCII is a subset of both CP-437 and UTF-8.

Upon successful completion, a pointer to the name is returned. Otherwise, NULL and the error code in archive is set to indicate the error.

zip_get_name() fails if:
index refers to a file that has been deleted (see zip_delete(3)).
index is not a valid file index in archive, or index points to an added file and ZIP_FL_UNCHANGED is set.
Required memory could not be allocated.

zip_get_name() was added in libzip 0.6. In libzip 0.10 the type of index was changed from int to zip_uint64_t. In libzip 0.11 the type of flags was changed from int to zip_flags_t.
