ZIP_SOURCE_FILE(3) Library Functions Manual ZIP_SOURCE_FILE(3)

NAME

zip_source_file, zip_source_file_createcreate 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 () and () 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, usually by () or ().

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 indicate the error.

ERRORS

zip_source_file() and zip_source_file_create() fail if:

[]
fname, start, or len are invalid.
[]
Required memory could not be allocated.
[]
Opening fname failed.
