The following macros check for certain structures or structure members.
| AC_STRUCT_ST_BLKSIZE | Macro |
If struct stat contains an st_blksize member, define
HAVE_STRUCT_STAT_ST_BLKSIZE. The former name,
HAVE_ST_BLKSIZE is to be avoided, as its support will cease in
the future. This macro is obsoleted, and should be replaced by
AC_CHECK_MEMBERS([struct stat.st_blksize]) |
| AC_STRUCT_ST_BLOCKS | Macro |
If struct stat contains an st_blocks member, define
HAVE_STRUCT STAT_ST_BLOCKS. Otherwise, require an
AC_LIBOBJ replacement of fileblocks. The former name,
HAVE_ST_BLOCKS is to be avoided, as its support will cease in the
future.
|
| AC_STRUCT_ST_RDEV | Macro |
If struct stat contains an st_rdev member, define
HAVE_STRUCT_STAT_ST_RDEV. The former name for this macro,
HAVE_ST_RDEV, is to be avoided as it will cease to be supported
in the future. Actually, even the new macro is obsolete, and should be
replaced by:
AC_CHECK_MEMBERS([struct stat.st_rdev]) |
| AC_STRUCT_TM | Macro |
If time.h does not define struct tm, define
TM_IN_SYS_TIME, which means that including sys/time.h
had better define struct tm.
|
| AC_STRUCT_TIMEZONE | Macro |
Figure out how to get the current timezone. If struct tm has a
tm_zone member, define HAVE_STRUCT_TM_TM_ZONE (and the
obsoleted HAVE_TM_ZONE). Otherwise, if the external array
tzname is found, define HAVE_TZNAME.
