get_ieee_interrupts(3I)

NAME
     GET_IEEE_INTERRUPTS - Retrieves flags that represent the current
     floating-point interrupt status

SYNOPSIS
     GET_IEEE_INTERRUPTS ([STATUS=]status)

STANDARDS
     Fortran extension

     IEEE Standard for Binary Floating-point Arithmetic

DESCRIPTION
     The GET_IEEE_INTERRUPTS intrinsic subroutine is typically called upon
     entry to a procedure to obtain a set of flags that represent the
     current floating-point interrupt status.  It accepts the following
     argument:

     status    Must be scalar and of an integer type that occupies a full
               word.  It is an INTENT(OUT) argument.

     For the names of all possible interrupts, see GET_IEEE_STATUS(3I).

     This subroutine increases program performance by capturing and then
     directly manipulating the status bits with bit manipulation
     operations.  This practice compromises portability, however.

     The name of this intrinsic cannot be passed as an argument.

     Some of the bits of status are set to indicate the floating-point
     interrupts that are currently enabled or currently disabled.  The
     state of any given interrupt can be determined using
     TEST_IEEE_INTERRUPT(3I) and can be altered using
     ENABLE_IEEE_INTERRUPT(3I) or DISABLE_IEEE_INTERRUPT(3I).

NOTES
     The IEEE intrinsic procedures use the named constants contained in a
     system module, so you must include the following statement in your
     program:

          USE FTN_IEEE_DEFINITIONS

EXAMPLES
     See the example on DISABLE_IEEE_INTERRUPT(3I).
