I don't know whether I should file a bug report on this issue.
Consider the following little program:
/* t.c */
#include <stdio.h>
#include <signal.h>
int
main( void)
{
sigset_t set;
sigpending( &set);
return 0;
}
Compiling and running it:
$ cc t.c
$ ./a.out
$
And trying to do the same with threads:
$ cc -pthread t.c
/var/tmp/ccs690421.o: In function `main':
/var/tmp/ccs690421.o(.text+0x1a): undefined reference to `sigpending'
$
However,
$ nm /usr/lib/libc_r.a | grep sigpending
sigpending.o:
00000040 T _thread_sys_sigpending
$
Apparently this one is not documented anywhere. Is it a missing alias
then? Or is one simply not allowed to use sigpending() with threads?
