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 functions in this module are from Section 2.4 Error Numbers.

SYNOPSIS

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 [INTEGER,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 default INTEGER. 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.

E2BIG: Arg list too long
EACCES: Permission denied
EAGAIN: Resource temporarily unavailable
EBADF: Bad file descriptor
EBUSY: Resource busy
ECHILD: No child process
EDEADLK: Resource deadlock avoided
EDOM: Domain error
EEXIST: File exists
EFAULT: Bad address
EFBIG: File too large
EINTR: Interrupted function call
EINVAL: Invalid argument
EIO: Input/Output error
EISDIR: Is a directory
EMFILE: Too many open files
EMLINK: Too many links
ENAMETOOLONG: Filename too long
ENFILE: Too many open files in system
ENODEV: No such device
ENOENT: No such file or directory
ENOEXEC: Exec format error
ENOLCK: No locks available
ENOMEM: Not enough space
ENOSPC: No space left on device
ENOSYS: Function not implemented
ENOTDIR: Not a directory
ENOTEMPTY: Directory not empty
ENOTTY: Inappropriate I/O control operation
ENXIO: No such device or address
EPERM: Operation not permitted
EPIPE: Broken pipe
ERANGE: Result too large
EROFS: Read-only file system
ESPIPE: Invalid seek
ESRCH: No such process
EXDEV: Improper link
