how to get the PID of the GDL session in linux?

[brandy125]

In linux I would do:

IDL> pid=call_external('/usr/local/itt/idl70/bin/bin.linux.x86_64/libidl.so','getpid',/cdecl)
IDL> print,pid
       84066

How can I do this in GDL?

[slayoo]

One way, likely not the simplest, would be:

GDL> spawn, 'echo $PPID', output & pid=fix(output) & print, pid
   30593
GDL> $ps | grep gdl$
  30593 pts/2    00:00:00 gdl

HTH

Perfect! Thanks!

My stupid question :

GDL> print, call_external('IDLetGDL/IDL88/idl88/bin/bin.linux.x86_64/libidl.so','getpid')
       10142

GDL> print, call_external('IDLetGDL/IDL88/idl88/bin/bin.linux.x86_64/libidl.so','getpid',/cdecl)
% CALL_EXTERNAL: Keyword parameter <CDE> not allowed in call to: CALL_EXTERNAL
% Execution halted at: $MAIN$          

GDL> #call_external
Internal FUNCTION : res=CALL_EXTERNAL([inf. Args],VALUE,ALL_VALUE,RETURN_TYPE,B_VALUE,I_VALUE,L_VALUE,F_VALUE,D_VALUE,
UI_VALUE,UL_VALUE,L64_VALUE,UL64_VALUE,S_VALUE,UNLOAD,ALL_GDL,STRUCT_ALIGN_BYTES,DEFAULT,PORTABLE,VAX_FLOAT)

and reading the doc., if I understand well, we just have to ignore /cdecl when running on Linux, isn't it ?

A.

Ps: last point I forgot to copy, on my linux :

IDL> print, call_external('IDLetGDL/IDL88/idl88/bin/bin.linux.x86_64/libidl.so','getpid')
       10811
IDL> print, call_external('IDLetGDL/IDL88/idl88/bin/bin.linux.x86_64/libidl.so','getpid',/cde)
       10811

OK, in PR #1713 I manage the fact that keyword /CDECL is silently ignored on Linux and OSX
and I mentioned we need more work on MSwin !

Well, on my linux it works with and without /cdecl I do not even remember any more why I put /cdecl at that time.

file_readlink('/proc/self')

This works in IDL/FL, but not in GDL :-(

this bug report is issue #1709 and should be solved in PR #1713
Thanks. Ideas for more tests welcome !
