setposix(3P)                                         setposix(3P)



     NAME
          setposix - set POSIX compatibility flags

     SYNOPSIS
          int setposix()

     DESCRIPTION
          setposix is equivalent to the following code fragment:

             #include <compat.h>
             setcompat(COMPAT_POSIX);

          COMPAT_POSIX is equivalent to all of the following:

             COMPAT_BSDGROUPS
             COMPAT_BSDCHOWN
             COMPAT_BSDSIGNALS
             COMPAT_BSDTTY
             COMPAT_SYSCALLS
             COMPAT_POSIXPATHTRUNC
             COMPAT_EXEC

          Any non-POSIX compatibility flags that were set prior to the
          call to setposix are reset.

     RETURN VALUE
          Upon successful completion, setposix returns the previous
          compatibility mask.  Otherwise, a value of -1 is returned
          and errno is set to indicate the error.

     ERRORS
          setposix will return the following error code:

          [EINVAL]  setposix results in a change in the state of the
                    COMPAT_BSDSIGNALS bit and a signal is currently
                    pending, caught, or held.
