Run-Time Library Routines

Intel® Fortran provides library modules containing the following routines:

• Routines that help you write programs for graphics, QuickWin, and other applications (in modules IFQWIN, IFLOGM, and IFCORE):

  • QuickWin routines (W*S)

  • Graphics routines (W*S)

  • Dialog routines (W*S)

  • Miscellaneous run-time routines

• Routines systems that help you write programs using Component Object Model (COM) and Automation servers (in modules IFCOM and IFAUTO):

  • COM routines (W*S)

  • AUTO routines (W*S)

• Portability routines that help you port your programs to or from other systems, or help you perform basic I/O to serial ports on Windows* systems (in module IFPORT).

• National Language Support routines that help you write foreign language programs for international markets (in module IFNLS). These routines are only available on Windows* systems.

• POSIX routines that help you write Fortran programs that comply with the POSIX* Standard (in module IFPOSIX).

• ESTABLISHQQ lets you specify a routine to handle Run-Time Library (RTL) errors (in module IFESTABLISH).

• FOR__SET_FTN_ALLOC lets you specify a user-defined routine to dynamically allocate commons. The caller of FOR__SET_FTN_ALLOC must include module IFCOMMONALLOC.

When you include the statement USE module-name in your program, these library routines are automatically linked to your program if called.

You can restrict what is accessed from a USE module by adding ONLY clauses to the USE statement.

Note that routines that are only available on Windows, including routines that are labeled as (W*S), are not available on Intel® MIC Architecture.
