SYNOPSIS


.In zip.h zip_file_t * zip_fopen zip_t *archive const char *fname zip_flags_t flags zip_file_t * zip_fopen_index zip_t *archive zip_uint64_t index zip_flags_t flags

DESCRIPTION

The zip_fopen function opens the file name fname in archive. The flags argument specifies how the name lookup should be done, according to the values are described in zip_name_locate(3). Also, the following values may be or ’ed to it.
ZIP_FL_COMPRESSED Read the compressed data. Otherwise the data is uncompressed by zip_fread.
ZIP_FL_UNCHANGED Read the original data from the zip archive, ignoring any changes made to the file.

The zip_fopen_index function opens the file at position index.

If encrypted data is encountered, the functions call zip_fopen_encrypted(3) or zip_fopen_index_encrypted(3) respectively, using the default password set with zip_set_default_password(3).

RETURN VALUES

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