Functions 3
This chapter presents C library function descriptions in alphabetical order. In these
descriptions, double means floating-point, double precision value.
You must include the appropriate header files in order to use the functions. The
description of each function lists the required include statements. To check the errno
value, you must include the header file.
Each C function (or group of related functions) contains a description with these
elements:
• Function heading
• Required #include statement(s)
• Function prototype(s)
• Description of argument(s)
• Description of behavior
• Description of successful returns followed by error returns
If ANSI appears in the function heading, this is an ANSI function. If DOS appears in
the function heading, this is a DOS function. If stdio appears, this is a stdio function,
which requires that the calling task has access to the standard streams: stdin, stdout,
and stderr, along with the necessary connections and memory requirements.
