In this chapter, you'll notice that many functions
are related to other functions.
This section arranges the functions into the following categories:
This subsection gives the header files that should be included within
a source file that references the function or macro.
It also shows an appropriate declaration for the function or for a
function that could be substituted for a macro.
This declaration isn't included in your program; only the header
file(s) should be included.
When a pointer argument is passed to a function, and that function doesn't
modify the item indicated by that pointer, then the argument is shown
with const before the argument. For example, the following
indicates that the array pointed at by string isn't changed:
This subsection describes the possible values that the function might
assign to the global variable errno.
This optional subsection consists of one or more examples of
the use of the function.
The examples are often just fragments of code (not complete programs)
for illustrative purposes.
This subsection provides an indication of where the function or macro
is commonly found. The following notation is used:
The Classification section also indicates whether or not it's safe to use the
function:
This optional subsection provides a list of related functions or
macros, or places to look for more information.
