The portability library is called libifport.a. Frequently used functions are included in a portability module called IFPORT. See these topics: Using the Portability Library libifport.a Portability Routines Using the Portability Library libifport.a You can use the portability library libifport.a in one of two ways: 228
Intel® Fortran Compiler for Linux* Systems User's Guide, Volume I: Building Applications • Add the statement USE IFPORT to your program. This statement includes the portability library libifport.a. • Call portability routines using the correct parameters and return value. libifport.a is passed to the linker by default during linking. To prevent libifport.a from being passed to the linker, specify the -fpscomp nolibs option. Using the libifport.a portability library provides interface blocks and parameter definitions for the routines, as well as compiler verification of calls. Some routines in this library can be called with different sets of arguments, and sometimes even as a function instead of a subroutine. In these cases, the arguments and calling mechanism determine the meaning of the routine. The libifport.a portability library contains generic interface blocks that give procedure definitions for these routines. Fortran 95/90 contains intrinsic procedures for many of the portability functions. The portability routines are extensions to the Fortran 95 standard. When writing new code, use Fortran 95/90 intrinsic procedures whenever possible (for portability and performance reasons). Portability Routines This section describes some of the portability routines and how to use them. For a complete list of the routines, see the table of Portability Routines in the Overview chapter of the Intel Fortran Libraries Reference. Information Retrieval Routines Information retrieval routines return information about system commands, command-line arguments, environment variables, and process or user information. Group, user, and process ID are INTEGER(4) variables. Login name and host name are character variables. The functions GETGID and GETUID are provided for portability, but always return 1.
