#pragma
is an implementation-defined directive that allows various instructions to be
given to the compiler. For example, a compiler may have an option that supports
program execution tracing. A trace option would then be specified by a #pragma statement.
You must check the compiler's documentation for details and options.
The #pragma directive provides a way to request
special behavior from the compiler. This directive is most useful for programs
that are unusually large or that need to take advantage of the capabilities of
a particular compiler. Pragmas are used within the source program.
#pragma token(s)
pragma is usually followed by a single token, which
represents a command for the compiler to obey. You should check the software
implementation of the C standard you intend on using for a list of the
supported tokens. Not surprisingly, the set of commands that can apear in
#pragma directives is different for each compiler; you'll have to consult the documentation
for your compiler to see which commands it allows and what those commands do.
For instance one of the most implemented preprocessor
directives, #pragma once when placed at the beginning of a header file,
indicates that the file where it resides will be skipped if included several
times by the preprocessor.
