NAME
libexplain - Explain errno values returned by libc functions
SYNOPSIS
cc ... -lexplain;
#include <libexplain/libexplain.h>
DESCRIPTION
The libexplain library exists to give explanations of error reported by system calls. The
error message returned by strerror(3) tend to be quite cryptic. By providing a specific
error report for each system call, a more detailed error message is possible, usually
identifying and describing the specific cause from amongst the numerous meanings each
errno value maps to.
Race Condition
The explanation of the cause of an error is dependent on the environment of the error to
remain unchanged, so that when libexplain gets around to looking for the cause, the cause
is still there. On a running system, and particularly a multi‐user system, this is not
always possible.
If an incorrect explanation is provided, it is possible that the cause is no longer
present.
Compiling
Assuming the library header files has been installed into /usr/include, and the library
files have been installed into /usr/lib, compiling against libexplain requires no special
-I options.
When linking your pograms, add -lexplain to the list of libraries at the end of your link
line.
cc ... -lexplain
When you configure your package with GNU Autoconf, you need the large file support macro
AC_SYS_LARGEFILE
If you aren't using GNU Autoconf, you will have to work out the needed large file support
requirements yourdelf.
There is a pkg‐config(1) package for you to use, too:
CFLAGS="$CFLAGS `pkg-config libexplain --cflags`" LIBS="$LIBS `pkg-config
libexplain --libs`"
This can make figuring out the command line requirements much easier.
Environment Variable
The EXPLAIN_OPTIONS environment variable may be used to control some of the content in the
messages. Options are separated by comma (“,”) characters.
There are three ways to set an option:
1. The form “name=value” may be used explicitly. The values “true” and “false” are used
for boolean options.
2. An option name alone is interpreted to mean “name=true”.
3. The form “no‐name” is interpreted to mean “name=false”.
The following options are available:
debug Additional debugging messages for libexplain developers. Not generally useful to
clients of the library.
Default: false.
extra‐device‐info
Additional information for block and character special devices is printed when
naming a file and its type.
Default: true
numeric‐errno
This option includes the numeric errno value in the message, e.g. “(2, ENOENT)”
rather than “(ENOENT)”. Disabling this option is generally of use in automated
testing, to prevent UNIX dialect differences from producing false negatives.
Default: true
dialect‐specific
This controls the presence of explanatory text specific to a particular UNIX
dialect. It also suppresses printing system specific maximums. Disabling this
option is generally of use in automated testing, to prevent UNIX dialect
differences from producing false negatives.
Default: true.
hanging‐indent
This controls the hanging indent depth used for error message wrapping. By
default no hanging indent is used, but this can sometimes obfuscate the end of one
error message and the beginning of another. A hanging indent results in
continuation lines starting with white spoace, similar to RFC822 headers. A value
of 0 means no hanging indent (all lines flush with left margin). A common value
to use is 4: it doesn't consume to much of each line, and it is a clear indent.
The program may choose to override the environment variable using the
explain_option_hanging_indent_set(3) function. The hanging indent is limited to
10% of the terminal width.
Default: 0
internal‐strerror
This option controls the source of system eror message texts. If false, it uses
strerorP(3) for the text. If true, it uses internal string for the text. This is
mostly of use for automated testing, to avoid false negatives induced by
inconsistencies across Unix implementations.
Default: false.
program‐name
This option controls the inclusion of the program name at the start of error
messages, by the explain_*_or_die and explain_*_on_error functions. This helps
users understand which command is throwing the error. Disabling this option may
be of some interest to script writers. Program developers can use the
explain_program_name_set(3) function to set the name of the command, if they wish
to override the name that libexplain would otherwise obtain from the operating
system. Program developers can use the explain_program_name_assemble(3) function
to trump this option.
Default: true.
symbolic‐mode‐bits
This option controls how permission mode bits are represented in error messages.
Setting this option to true will cause symbolic names to be printed (e.g. S_IRUSR
| S_IWUSR | S_IRGRP | S_IROTH). Setting this option to false will cause octal
values to be printed (e.g. 0644).
Default: false.
