strpbrk_esq() and strdup_esq() are new variants for strpbrk() and
strdup() which handles escaped characters and quoted strings.
- strpbrk_esq() searches specified set of characters but ignores the
escaped characters and quoted strings.
e.g. strpbrk_esq("'quote\d' \queue quiz", "qd") returns "quiz".
- strdup_esq() duplicates string but removes backslash and quotes which
is used for quotation. It also keeps the string (including backslash)
in the quoted part.
e.g. strdup_esq("'quote\d' \queue quiz") returns "quote\d queue quiz".
The (single, double) quotes in the quoted part should be escaped by
backslash. In this case, strdup_esq() removes that backslash.
The same quotes must be paired. If you use double quotation, you need
to use the double quotation to close the quoted part.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
