If the B<v> is zero then an empty memory BIO will return EOF (that is 48it will return zero and BIO_should_retry(b) will be false. If B<v> is non 49zero then it will return B<v> when it is empty and it will set the read retry 50flag (that is BIO_read_retry(b) is true). To avoid ambiguity with a normal 51positive return value B<v> should be set to a negative value, typically -1. 52 | 1=pod 2 3=head1 NAME 4 5BIO_s_mem, BIO_set_mem_eof_return, BIO_get_mem_data, BIO_set_mem_buf, 6BIO_get_mem_ptr, BIO_new_mem_buf - memory BIO 7 8=head1 SYNOPSIS --- 36 unchanged lines hidden (view full) --- 45 46BIO_set_mem_eof_return() sets the behaviour of memory BIO B<b> when it is 47empty.
