Refactor, separate docs from headers, add ru docs
Doxygen kind'a sucks and I need multilanguage documentation, so I did that. Also, separated massive Math.h file into smaller files.

|

|

=head1 DESCRIPTION
|
||||
|
||||
The BH_Args library is designed for convenient handling of command line
|
||||
arguments in programs. It allows you to define a set of options that can be
|
||||
specified when starting a program and provides mechanisms for their analysis and
|
||||
processing.
|
||||
|
||||
Argument parsing follows these rules:
|
||||
|
||||
=over
|
||||
|
||||
=item *
|
||||
|
||||
If the "--" argument is specified, subsequent argument parsing is stopped.
|
||||
|
||||
=item *
|
||||
|
||||
If the "-" argument is specified, it is processed as is.
|
||||
|
||||
=item *
|
||||
|
||||
For long argument values, the string after the equal sign or the next argument
|
||||
("--define=value" or "--define value") will be used.
|
||||
|
||||
=item *
|
||||
|
||||
For short argument values, the remainder of the string after the parameter
|
||||
character or the next argument ("-dvalue" or "-d value") will be used.

char **argv,
|
||||
BH_ArgsOption *options,
|
||||
BH_ArgsCallback callback,
|
||||
void *data);
|
||||
|
||||
Parses the command line arguments I<options> (specified in I<argc> and I<argv>)
|
||||
and calls the specified handler I<callback> (with user data I<data>).
|
||||
|
||||
The I<options> parameter refers to a null-terminated array.
|
||||
|
||||
If successful, this function returns 0, otherwise it returns an error code.
|
||||
|
||||
|
||||
=head2 BH_ArgsHelp
|
||||
|

void BH_ArgsHelp(BH_ArgsOption *options,
|

int padding);
|
||||
|
||||
Prints help information for the arguments I<options> to F<stdout> (with the
|
||||
specified alignment I<padding>).
|
||||
|
||||
If the I<padding> parameter is 0, the default value (30) will be used.

const char *name;
|

int flags;
|

const char *description;
|
||||
} BH_ArgsOption;
|
||||
|
||||
The I<key> field contains the option identifier. If the I<key> identifier is a
|
||||
printable ASCII character, it will be used as a short argument.
|
||||
|
||||
The optional I<name> field contains a string that will be used as a long
|
||||
argument.
|
||||
|
||||
The I<flags> field contains argument flags. A combination of the following flags
|

is possible:
|

|

=over
|

|

=item B<BH_ARGS_VALUE>
|

|

The argument accepts a value.
|

|
||||
|
||||
The argument value is optional.
|
||||
|
||||
=back
|
||||
|
||||
The I<description> field contains a string that will be used when displaying
|
||||
help information using the L</BH_ArgsHelp> function.

=head1 NAME
|
||||
|
||||
BH_IO - I/O subsystem
|
||||
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
#include <BH/io.h>
|
||||
|
||||
BH_IO *io = BH_FileNew("input.txt", BH_FILE_WRITE | BH_FILE_TRUNCATE, NULL);
|
||||
BH_IOWrite(io, "Hello, world!", 13, NULL);
|
||||
BH_IOFree(io);

||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
BH_IO provides a subsystem that allows you to work with various objects (files,
|
||||
sockets, memory) via a single I/O interface. This allows you to write code that
|
||||
is not tied to a specific input/output system.
|
||||
|
||||
It is guaranteed that any BH_IO object supports the following operations:
|
||||
L</BH_IORead>, L</BH_IOWrite>, L</BH_IOCtl> и L</BH_IOCap>.
|
||||
|
||||
Depending on the implementation of a particular BH_IO object, additional
|
||||
operations may be available: L</BH_IOFlags>, L</BH_IOClear>, L</BH_IOFlush>,
|
||||
L</BH_IOSize>, L</BH_IOTell>, L</BH_IOSeek>, L</BH_IOPeek> and others.
|
||||
|
||||
By default, the I/O subsystem allows you to work with files (L</BH_FileNew>) or
|
||||
RAM (L</BH_BytesNew>), as well as buffer I/O (L</BH_BufferNew>).
|
||||
|
||||
|
||||
=head1 EXTENSIONS

=head1 DESCRIPTION
|
||||
|
||||
The BH_String library provides a set of functions for working with strings,
|
||||
including converting numbers to strings and back.
|
||||
|
||||
|
||||
=head1 DEFINING THE BASE
|
||||
|
||||
The functions of the I<StringToInt> family have an algorithm for determining the
|
||||
base of a number by string prefixes:
|
||||
|
||||
=over
|
||||
|
||||
=item *
|
||||
|
||||
If the prefix I<0b>, then base 2
|
||||
|
||||
=item *
|
||||
|
||||
If the prefix I<0>, then base 8
|
||||
|
||||
=item *
|
||||
|
||||
If the prefix I<0x>, then base 16
|
||||
|
||||
=item *
|
||||
|
||||
Otherwise, base 10.
|
||||
|
||||
=back

||||
size_t *actual);

|
||||

|
||||
(with a length limit of I<size>).
|
||||
|
||||
The I<format> parameter specifies the format for converting a number to a
|
||||
string. Acceptable formats:
|

|
||||
|
||||
Fixed format: [-]ddd.ddd
|

|
||||
|
||||
Fixed or scientific format, depending on which one is shorter.
|
||||
|
||||
=back
|
||||
|
||||
The I<precision> parameter sets the precision of converting a number to a
|
||||
string. If the accuracy value is negative, the conversion will be performed with
|
||||
the minimum required accuracy so that the reverse conversion results in the
|
||||
original number.

|
||||
The optional parameter I<actual> returns the length of the recorded string.
