CCS C Compiler Manual PCB / PCM / PCH

PREPROCESSOR
PRE-PROCESSOR DIRECTORY
Pre-processor directives all begin with a # and are followed by a specific command. Syntax is
dependent on the command. Many commands do not allow other syntactical elements on the
remainder of the line. A table of commands and a description is listed on the previous page.
Several of the pre-processor directives are extensions to standard C. C provides a preprocessor
directive that compilers will accept and ignore or act upon the following data. This
implementation will allow any pre-processor directives to begin with #PRAGMA. To be
compatible with other compilers, this may be used before non-standard features.
Examples:
Both of the following are valid
#INLINE
#PRAGMA INLINE

#IF expr #DEFINE #LIST
