-.TH errno 3 2023-10-31 "Linux man-pages 6.7"
-.SH NAME
-errno \- number of last error
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.B #include <errno.h>
-.\".P
-.\".BI "extern int " errno ;
-.fi
-.SH DESCRIPTION
-The
-.I <errno.h>
-header file defines the integer variable
-.IR errno ,
-which is set by system calls and some library functions in the event
-of an error to indicate what went wrong.
-.\"
-.SS errno
-The value in
-.I errno
-is significant only when the return value of
-the call indicated an error
-(i.e., \-1 from most system calls;
-\-1 or NULL from most library functions);
-a function that succeeds
-.I is
-allowed to change
-.IR errno .
-The value of
-.I errno
-is never set to zero by any system call or library function.
-.P
-For some system calls and library functions (e.g.,
-.BR getpriority (2)),
-\-1 is a valid return on success.
-In such cases, a successful return can be distinguished from an error
-return by setting
-.I errno
-to zero before the call, and then,
-if the call returns a status that indicates that an error
-may have occurred, checking to see if
-.I errno
-has a nonzero value.
-.P
-.I errno
-is defined by the ISO C standard to be a modifiable lvalue
-of type
-.IR int ,
-and must not be explicitly declared;
-.I errno
-may be a macro.
-.I errno
-is thread-local; setting it in one thread
-does not affect its value in any other thread.
-.\"
-.SS Error numbers and names
-Valid error numbers are all positive numbers.
-The
-.I <errno.h>
-header file defines symbolic names for each
-of the possible error numbers that may appear in
-.IR errno .
-.P
-All the error names specified by POSIX.1
-must have distinct values, with the exception of
-.B EAGAIN
-and
-.BR EWOULDBLOCK ,
-which may be the same.
-On Linux, these two have the same value on all architectures.
-.P
-The error numbers that correspond to each symbolic name
-vary across UNIX systems,
-and even across different architectures on Linux.
-Therefore, numeric values are not included as part of the list of
-error names below.
-The
-.BR perror (3)
-and
-.BR strerror (3)
-functions can be used to convert these names to
-corresponding textual error messages.
-.P
-On any particular Linux system,
-one can obtain a list of all symbolic error names and
-the corresponding error numbers using the
-.BR errno (1)
-command (part of the
-.I moreutils
-package):
-.P
-.in +4n
-.EX
-$ \fBerrno \-l\fP
-EPERM 1 Operation not permitted
-ENOENT 2 No such file or directory
-ESRCH 3 No such process
-EINTR 4 Interrupted system call
-EIO 5 Input/output error
-\&...
-.EE
-.in
-.P
-The
-.BR errno (1)
-command can also be used to look up individual error numbers and names,
-and to search for errors using strings from the error description,
-as in the following examples:
-.P
-.in +4n
-.EX
-$ \fBerrno 2\fP
-ENOENT 2 No such file or directory
-$ \fBerrno ESRCH\fP
-ESRCH 3 No such process
-$ \fBerrno \-s permission\fP

-.\" POSIX.1 (2001 edition) lists the following symbolic error names.  Of
-.\" these, \fBEDOM\fP and \fBERANGE\fP are in the ISO C standard.  ISO C
-.\" Amendment 1 defines the additional error number \fBEILSEQ\fP for
-.\" coding errors in multibyte or wide characters.

-.SH NOTES
-A common mistake is to do
-.P
-.in +4n
-.EX
-if (somecall() == \-1) {
-    printf("somecall() failed\en");
-    if (errno == ...) { ... }
-}
-.EE
-.in
-.P
-where
-.I errno
-no longer needs to have the value it had upon return from
-.IR somecall ()
-(i.e., it may have been changed by the
-.BR printf (3)).
-If the value of
-.I errno
-should be preserved across a library call, it must be saved:
-.P
-.in +4n
-.EX
-if (somecall() == \-1) {
-    int errsv = errno;
-    printf("somecall() failed\en");
-    if (errsv == ...) { ... }
-}
-.EE
-.in
-.P
-Note that the POSIX threads APIs do
-.I not
-set
-.I errno
-on error.
-Instead, on failure they return an error number as the function result.
-These error numbers have the same meanings as the error numbers returned in
-.I errno
-by other APIs.
-.P
-On some ancient systems,
-.I <errno.h>
-was not present or did not declare
-.IR errno ,
-so that it was necessary to declare
-.I errno
-manually
-(i.e.,
-.IR "extern int errno" ).
-.BR "Do not do this" .
-It long ago ceased to be necessary,
-and it will cause problems with modern versions of the C library.
