F90_UNIX_ERRNO(3)

NAME
f90_unix_errno — Module of Unix error codes

USAGE
USE F90_UNIX_ERRNO

This module contains part of a Fortran API to functions detailed in ISO/IEC 9945-1:1990 Portable Operating System Interface (POSIX) - Part 1: System Application Program Interface (API) [C Language].

The facilities in this module are from Section 2.4 Error Numbers.

SYNOPSIS

Kind Parameter
    ERROR_KIND.

Error Parameters
    E2BIG, EACCES, EAGAIN, EBADF, EBUSY, ECHILD, EDEADLK, EDOM, EEXIST, EFAULT, EFBIG, EINTR, EINVAL, EIO, EISDIR, EMFILE, EMLINK, ENAMETOOLONG, ENFILE, ENODEV, ENOENT, ENOEXEC, ENOLCK, ENOMEM, ENOSPC, ENOSYS, ENOTDIR, ENOTEMPTY, ENOTTY, ENXIO, EPERM, EPIPE, ERANGE, EROFS, ESPIPE, ESRCH, EXDEV.

ERROR HANDLING

Many procedures provided by the F90_UNIX_* modules have an optional ERRNO argument, declared as

INTEGER(error_kind),OPTIONAL,INTENT(OUT)
If this argument is provided it receives the error status from the procedure; zero indicates successful completion, otherwise it will be a non-zero error code, usually one of the ones listed in this module.

If the ERRNO argument is omitted and an error condition is raised, the program will be terminated with an informative error message.

If a procedure has no ERRNO argument it indicates that no error condition is possible - the procedure always succeeds.

PARAMETER DESCRIPTION

All parameters are of type INTEGER with kind ERROR_KIND. The following table lists the error message typically associated with each error code; for full details see ISO/IEC 9945-1:1990, either section 2.4 or the appropriate section for the function raising the error.

    Resource deadlock avoided

EDOM
    Domain error

EEXIST
    File exists
