# Syntax rules for the C (and partially C++) programming languages.
 
#
# Rewritten and extended with defines by Morthimer McMare
#    <mailto:morthimer_second@list.ru>
#
# Tab size: 4.
# Feel free to improve the highlighting file.
#
# Date:
#   Initial 2024.04.24;
#   Updated 2024.06.26 (first public release. Classic Midnight Commander C-syntax theme set by default, added keywords from the C23 standard).
#
 
 
# For the default (blue) background.
# The colors almost match the original "c.syntax" file, slightly extending it:
