| Summary | 0000066: sigaction/signal lists are different | |||||||||||
| Description |
COMMENT Enhancement Request Number 4 tydeman:xxxxxxxxx Bug in XSHd5.1 sigaction() (rdvk# 6) {sigaction-signal} Thu, 24 Jul 2008 17:15:56 +0100 (BST) _____________________________________________________________________________ sigaction() at line 61039 lists abort(), kill(), raise(). While signal() at line 61636 lists abort(), raise(), kill(), pthread_killl(), and sigqueue(). Seems strange to have a different list of functions. |
|||||||||||
| Desired Action |
Review the list of exceptional functions for signal() and sigaction() to make sure they should be different. |

Interpretation response ------------------------ The standard states the requirements for sigaction and signals and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor." Rationale: ------------- None. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- On signal() D5.1R pg 1937 61636 replace the para with [CX]If the process is multithreaded[/CX], or if the process is single threaded and a signal handler is executed other than as the result of: * the process calling abort(), raise(), [CX]kill(), pthread_kill(), or sigqueue()[/CX] to generate a signal that is not blocked, or * [CX]a pending signal being unblocked and being delivered before the call that unblocked it returns[/CX] the behavior is undefined if the signal handler refers to any object [CX]other than errno[/CX] with static storage duration other than by assigning a value to an object declared as volatile sig_atomic_t, or if the signal handler calls any function defined in this standard other than [CX]one of the functions listed in Section 2.4 (on page xxx)[/CX]. Also copy the above to 2.4.3 without CX shading Replacing 16719-16721 "When signal-catching functions are invoked asynchronously with process execution, the behavior of some of the functions defined by this volume of POSIX.1-200x is unspecified if they are called from a signal-catching function." and change the last piece of the new replacement to in this standard other than one of the functions listed in the following table: also delete the paragraph in APP USAGE On sigaction Page: 1919 Line: 61039 (Target for TC1) |
