npassert.h
|
||
|
|
NP environment independent assertion/logging routines
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
|
||
|
|
ASSERT(exp) Evaluates its argument. If "exp" evals to
|
||
|
|
FALSE, then the app will terminate, naming
|
||
|
|
the file name and line number of the assertion
|
||
|
|
in the source.
|
||
|
|
|
||
|
|
UIASSERT(exp) Synonym for ASSERT.
|
||
|
|
|
||
|
|
ASSERTSZ(exp,sz) As ASSERT, except will also print the message
|
||
|
|
"sz" with the assertion message should it fail.
|
||
|
|
|
||
|
|
REQUIRE(exp) As ASSERT, except that its expression is still
|
||
|
|
evaluated in retail versions. (Other versions
|
||
|
|
of ASSERT disappear completely in retail builds.)
|
||
|
|
|
||
|
|
ANSI_ASSERTABLE(sz) Declares "sz" to be a string buffer which
|
||
|
|
can be used with the ASSERT_ANSI and ASSERT_OEM
|
||
|
|
macros (effectively declares a debug-only BOOL
|
||
|
|
associated with the string).
|
||
|
|
|
||
|
|
ASSERT_ANSI(sz) Asserts that sz is in the ANSI character set.
|
||
|
|
|
||
|
|
ASSERT_OEM(sz) Asserts that sz is in the OEM character set.
|
||
|
|
|
||
|
|
IS_ANSI(sz) Declares that sz is in the ANSI character set
|
||
|
|
(e.g., if it's just come back from a GetWindowText).
|
||
|
|
|
||
|
|
IS_OEM(sz) Declares that sz is in the OEM character set.
|
||
|
|
|
||
|
|
TO_ANSI(sz) Does OemToAnsi in place.
|
||
|
|
|
||
|
|
TO_OEM(sz) Does AnsiToOem in place.
|
||
|
|
|
||
|
|
COPY_TO_ANSI(src,dest) Does OemToAnsi, not in place.
|
||
|
|
|
||
|
|
COPY_TO_OEM(src,dest) Does AnsiToOem, not in place.
|
||
|
|
|
||
|
|
NOTE: the latter two, just like the APIs themselves, have the
|
||
|
|
source first and destination second, opposite from strcpy().
|
||
|
|
|
||
|
|
The ASSERT macros expect a symbol _FILENAME_DEFINED_ONCE, and will
|
||
|
|
use the value of that symbol as the filename if found; otherwise,
|
||
|
|
they will emit a new copy of the filename, using the ANSI C __FILE__
|
||
|
|
macro. A client sourcefile may therefore define __FILENAME_DEFINED_ONCE
|
||
|
|
in order to minimize the DGROUP footprint of a number of ASSERTs.
|
||
|
|
|
||
|
|
FILE HISTORY:
|
||
|
|
Johnl 11/15/90 Converted from CAssert to general purpose
|
||
|
|
Johnl 12/06/90 Changed _FAR_ to _far in _assert prototype
|
||
|
|
beng 04/30/91 Made C-includable
|
||
|
|
beng 08/05/91 Made assertions occupy less dgroup; withdrew
|
||
|
|
explicit heapchecking (which was crt
|
||
|
|
dependent anyway)
|
||
|
|
beng 09/17/91 Removed additional consistency checks;
|
||
|
|
rewrote to minimize dgroup footprint,
|
||
|
|
check expression in-line
|
||
|
|
beng 09/19/91 Fixed my own over-cleverness
|
||
|
|
beng 09/25/91 Fixed bug in retail REQUIRE
|
||
|
|
gregj 03/23/93 Ported to Chicago environment
|
||
|
|
gregj 05/11/93 Added ANSI/OEM asserting routines
|
||
|
|
gregj 05/25/93 Added COPY_TO_ANSI and COPY_TO_OEM
