Miscellaneous Run-Time Library Routines

The following table lists miscellaneous run-time library routines.

Programs that use most of these routines should contain a USE IFCORE statement to obtain the proper interfaces to these routines.

Name	Procedure Type	Description
COMMITQQ	Function	Forces the operating system to execute any pending write operations for a file.
FOR_DESCRIPTOR_ASSIGN ^¹	Subroutine	Creates an array descriptor in memory.
FOR_GET_FPE	Function	Returns the current settings of floating-point exception flags.
for_rtl_finish_ ^²	Function	Cleans up the Fortran run-time environment.
for_rtl_init_ ^²	Function	Initializes the Fortran run-time environment.
FOR_SET_FPE	Function	Sets the floating-point exception flags.
FOR__SET_FTN_ALLOC	Function	Tells the Fortran Run-Time Library (RTL) to use a user-defined routine to dynamically allocate commons.
FOR_SET_REENTRANCY	Function	Controls the type of reentrancy protection that the Fortran Run-Time Library (RTL) exhibits.
GERROR	Subroutine	Returns a message for the last error detected by a Fortran run-time routine.
GETCHARQQ	Function	Returns the next keystroke.
GETEXCEPTIONPTRSQQ ^¹	Function	Returns a pointer to C run-time exception information pointers appropriate for use in signal handlers established with SIGNALQQ or direct calls to the C rtl signal( ) routine.
GETSTRQQ	Function	Reads a character string from the keyboard using buffered input.
PEEKCHARQQ	Function	Checks the buffer to see if a keystroke is waiting.
PERROR	Subroutine	Sends a message to the standard error stream, preceded by a specified string, for the last detected error.
TRACEBACKQQ	Subroutine	Provides traceback information.
¹ W*S ² You do not need a USE IFCORE statement for this routine.
