Project : eterm
Module : libast
Dir : eterm/libast/include
Modified Files:
libast.h
Log Message:
Mon Nov 10 14:28:09 2003 Michael Jennings (mej)
Added assertions/requirements for string member functions.
Changed pointer printouts to %010p instead of %8p, since the latter
didn't account for the possibility of a leading "0x".
Fixed typos in hex_dump().
