* strports.c (scm_strprint_obj): simplify. start with initial buffer size of 0. (st_seek): don't allow string to be extended if seeking past the end of a read-only port. 1999-07-12 Gary Houston <ghouston@easynet.co.uk> * strports.c (st_seek): change the resize checks. * ports.c (scm_ftruncate): throw error if offset works out negative. * strports.c (st_flush): increase string size in blocks of SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if it's greater and reset read_buf_size. (scm_mkstrport): set rw_randow if only writing, since read_buf needs to be maintained for output ports too (it holds the written part of the string, while write_buf may have unwritten buffer chars.) (st_truncate): rewritten. (top of file): added a few notes. 1999-07-06 Gary Houston <ghouston@easynet.co.uk> * strports.c (st_grow_port): set pt->read_pos. set pt->read_buf_size one less than pt->write_buf_size if there's an unwritten char at the end of the string. similarly for pt->read_end. (st_resize_port): renamed from st_grow_port. (st_seek): simplify by assuming that pt->write_pos == pt->read_pos. seek from read_end instead of write_end for SEEK_END. (st_ftruncate): calculate current length using readbuf, not write buf. (scm_strport_to_string): use read_buf_size for length. (stfill_buffer): don't re-initialise the readbuf. 1999-07-05 Gary Houston <ghouston@easynet.co.uk> * strports.c (scm_strport_to_string): new procedure. (scm_call_with_output_string, scm_strprint_obj): use scm_strport_to_string. used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
