ierrno
PERROR(3F)PERROR(3F)NAME
perror, gerror, ierrno - get system error messages
SYNOPSIS
subroutine perror (string)
character*(*) string
subroutine gerror (string)
character*(*) string
character*(*) function gerror()
function ierrno()
DESCRIPTION
Perror will write a message to fortran logical unit 0 appropriate to the last detected system error. String will be written preceding the
standard error message.
Gerror returns the system error message in character variable string. Gerror may be called either as a subroutine or as a function.
Ierrno will return the error number of the last detected system error. This number is updated only when an error actually occurs. Most
routines and I/O statements that might generate such errors return an error code after the call; that value is a more reliable indicator of
what caused the error condition.
FILES
/usr/lib/libU77.a
SEE ALSO intro(2), perror(3)
D. L. Wasley, Introduction to the f77 I/O Library
BUGS
String in the call to perror can be no longer than 127 characters.
The length of the string returned by gerror is determined by the calling program.
NOTES
UNIX system error codes are described in intro(2). The f77 I/O error codes and their meanings are:
100 ``error in format''
101 ``illegal unit number''
102 ``formatted i/o not allowed''
103 ``unformatted i/o not allowed''
104 ``direct i/o not allowed''
105 ``sequential i/o not allowed''
106 ``can't backspace file''
107 ``off beginning of record''
108 ``can't stat file''
109 ``no * after repeat count''
110 ``off end of record''
111 ``truncation failed''
112 ``incomprehensible list input''
113 ``out of free space''
114 ``unit not connected''
115 ``invalid data for integer format term''
116 ``invalid data for logical format term''
117 ``'new' file exists''
118 ``can't find 'old' file''
119 ``opening too many files or unknown system error''
120 ``requires seek ability''
121 ``illegal argument''
122 ``negative repeat count''
123 ``illegal operation for unit''
124 ``invalid data for d, e, f, or g format term''
