Bug#728240: libc6: S_IFMT constants not included when _POSIX_C_SOURCE is defined as 200112L
Package: libc6
Version: 2.17-93
Severity: normal
The man page for stat states
POSIX.1-1990 did not describe the S_IFMT, S_IFSOCK, S_IFLNK, S_IFREG,
S_IFBLK,
S_IFDIR, S_IFCHR, S_IFIFO, S_ISVTX constants, but instead demanded the
use of the
macros S_ISDIR(), etc. The S_IF* constants are present in POSIX.1-2001
and later.
However, when I write the following program:
#define _POSIX_C_SOURCE 200112L
#include <sys/stat.h>
#include <stdio.h>
int main(void)
{
printf("%d\n", S_IFMT);
return 0;
}
and compile
[camomile:~]% gcc -o foo foo.c
foo.c: In function ‘main’:
foo.c:9:17: error: ‘S_IFMT’ undeclared (first use in this function)
printf("%d\n", S_IFMT);
^
foo.c:9:17: note: each undeclared identifier is reported only once for
each function it appears in
