NAME

       zip_source_file - create data source from a file

LIBRARY

       libzip (-lzip)

SYNOPSIS

       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.
