NAME

       zip_source_file - create data source from a file

LIBRARY

       libzip (-lzip)

SYNOPSIS

       struct zip_source * zip_source_file(struct zip *archive, const char *fname); "zip_uint64_t
       start" "zip_int64_t len"

DESCRIPTION

       The function zip_source_file creates a zip source  from  a  file.   zip_source_file  opens
       fname  and  reads  len bytes from offset start from it.  If len is 0 or -1, the whole file
       (starting from start ) is used.

       The fie is opened and read when the data from the source is used, usually by zip_close.

RETURN VALUES

       Upon successful completion, the created source is returned.  Otherwise, NULL  is  returned
       and the error code in archive is set to indicate the error.

ERRORS

       zip_source_file fails if:

              [ZIP_ER_INVAL]
                  fname, start, or len are invalid.

              [ZIP_ER_MEMORY]
                  Required memory could not be allocated.

              [ZIP_ER_OPEN]
