Error checking on Linux

[GoneFishing]

Hi,

Attachment contains sources and binaries for 3 small  programs:

Error :  prints out all known  errno's  and corresponding error messages
fnf      :  tries to open non-existent file and shows error message by calling error , error_at_line or perror   
             depending on user choice ( read comments in fnf.asm )
fnfc    : tries to open non-existent file and shows error message . Demonstrates usage of GCC magic constant  -   
             __FUNCTION__

NOTE: UASM has new builtin variable @ProcLine . Would it be logical to implement something like
                       @CurrProc or @ProcName   ?

@Line has been around for a while, and @ProcName can be implemented in the PROLOG:

Code Select Expand

include \Masm32\MasmBasic\Res\JBasic.inc ; ## console demo, builds in 32- or 64-bit mode with ML, UAsm, AsmC ##
.code
MyTest proc
  nop
  % echo ## the name of this procedure is jbProc$ ## ; see build output
  tmp$ CATSTR <Str$("This is proc >, jbProc$, < starting in line %i\n", jbPrologRun)>
  Print tmp$
  ret
MyTest endp
Init ; OPT_64 1 ; 1=use 64 bit assembly
  PrintLine Chr$("This code was assembled with ", @AsmUsed$(1), " in ", jbit$, "-bit format")
  jinvoke MyTest
  Inkey "That was easy"
EndOfCode

Output:

Code Select Expand

This code was assembled with ml64 in 64-bit format
This is proc MyTest starting in line 3
That was easy

@Line has been around for a while ...

@ProcLine is a little bit different :

@ProcLine, indicates the current source code line number relative to the start of the current procedure. 

Can you post source code for your jbProc ?

[jj2007]

Relative to the proc start is easy. too:

Code Select Expand

include \Masm32\MasmBasic\Res\JBasic.inc ; ## console demo, builds in 32- or 64-bit mode with ML, UAsm, AsmC ##

.code
MyTest proc
  nop
  % echo ## the name of this procedure is jbProc$ ## ; see build output
  tmp$ CATSTR <Str$("This is proc >, jbProc$, < starting in line %i\n", @Line-jbPrologRun)>
  Print tmp$
  ret
MyTest endp

Output:

Code Select Expand

This is proc MyTest starting in line 4

Can you post source code for your jbProc ?

It's included in the MasmBasic package as \Masm32\MasmBasic\Res\JBasic.inc

Thanks. I'll look into JBasic.inc

Now let's wait for  JOHNSA 

EDIT: Oh, I've forgotten that I had already played with this kind of helper macro for obtaining proc name. It was easy.  Still having   builtin little magic trick like  @ProcName or @CurrProcName or @ProcCurr would be great !

[johnsa]

Hey,

We can definitely add it in. I will do so and include it in the next update. @ProcName ok with everyone?

[johnsa]

@ProcName is in,  the stack alignment issue is sorted and a bunch of other pending changes. 2.46.6 packages are up :)

Great!
I'll  check it tomorrow .
