NAMEPXFSLEEP - Delays process execution
SYNOPSIS
SUBROUTINE PXFSLEEP(iseconds, isecleft, ierror)
INTEGER iseconds, isecleft, ierror
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
DESCRIPTION
The PXFSLEEP subroutine waits iseconds before generating a SIGALRM
signal. If a previous PXFSLEEP has time remaining, isecleft contains
the number of seconds until the signal SIGALRM would have been
generated.
The following is a list of arguments for this routine:
iseconds Default integer input variable containing the number of
real-time seconds to wait before sending the calling process
a SIGALRM signal.
isecleft Default integer output variable containing the number of
seconds left until a previous request would have generated a
SIGALRM signal.
ierror Default integer output variable containing a status of zero
if PXFSLEEP was successful.
On IRIX systems, this routine is in libfortran.so which is linked by
default when compiling programs with the MIPSpro 7 Fortran 90 compiler
or when compiling programs with the -craylibs option to the MIPSpro
7.2 F77 compiler.
When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
kind unless documented otherwise. On UNICOS and UNICOS/mk, default
kind is KIND=8 for integer, real, complex, and logical arguments; on
IRIX systems, the default kind is KIND=4.
NOTES
Replace the use of the sleep(3C) function with the subroutine call to
PXFSLEEP().
EXAMPLES
program pxftest
integer iseconds, isecleft, ierror
iseconds = 10
isecleft = 0
ierror = 0
CALL PXFSLEEP(iseconds, isecleft, ierror)
if (ierror .ne. 0) then
print *,'FAILED: PXFSLEEP call failed with error = ',ierror
else
print *,'PASSED: PXFSLEEP call returned no error'
endif
if (isecleft .ne. 0) then
print *,'FAILED: PXFSLEEP, isecleft not zero, =',isecleft
endif
end
