zip_source_file

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 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, usually 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 indicate 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.
