ZIP_SOURCE_FILE(3) BSD Library Functions Manual ZIP_SOURCE_FILE(3)
NAME
zip_source_file, zip_source_file_create — create data source from a file
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
zip_source_t *
zip_source_file(zip_t *archive, const char *fname, zip_uint64_t start,
zip_int64_t len);
zip_source_t *
zip_source_file_create(const char *fname, zip_uint64_t start,
zip_int64_t len, zip_error_t *error);
DESCRIPTION
The functions zip_source_file() and zip_source_file_create() create a zip
source from a file. They open fname and read len bytes from offset start
from it. If len is 0 or -1, the whole file (starting from start) is
used.
If the file supports seek, the source can be used to open a zip archive
from.
The file is opened and read when the data from the source is used, usu-
ally by zip_close() or zip_open_from_source().
RETURN VALUES
Upon successful completion, the created source is returned. Otherwise,
NULL is returned and the error code in archive or error is set to indi-
cate the error.
ERRORS
zip_source_file() and zip_source_file_create() fail if:
[ZIP_ER_INVAL] fname, start, or len are invalid.
[ZIP_ER_MEMORY] Required memory could not be allocated.
[ZIP_ER_OPEN] Opening fname failed.
