Bug 22479 – Syntax error in macro for pthread_cleanup_push -- pthread.h

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Joshua Moore-Oliva 2003-06-09 03:38:25 UTC]

There is an error in the macro for pthread_cleanup_push. 
 
Right now it is 
 
#define pthread_cleanup_push(routine,arg) \ 
  { struct _pthread_cleanup_buffer _buffer;                                   \ 
    _pthread_cleanup_push (&_buffer, (routine), (arg)); 
 
while it should be 
 
#define pthread_cleanup_push(routine,arg) \ 
  { struct _pthread_cleanup_buffer _buffer;                                   \ 
    _pthread_cleanup_push (&_buffer, (routine), (arg)); } 
 
 
Note that it is currently missing a closing }

this is in what package?

[Comment 2 Joshua Moore-Oliva 2003-06-09 08:09:17 UTC]

I have no idea what package holds the headers for the system, I only know that my gentoo box 
has that problem on it and I've never touched the system headers before.

This is not a bug, it is intentional feature of the header files, read the comments in pthread.h:

  pthread_cleanup_push and pthread_cleanup_pop are macros and must always
   be used in matching pairs at the same nesting level of braces.

Thus pthread_cleanup_push opens a brace and pthread_cleanup_pop closes the brace,
