NAME
intro - Introduction to device drivers
DESCRIPTION
This section describes the routines that can directly call device drivers
from programs in user space. The descriptions can include the following
sections.
Name
This section lists the name of the routine and a summary of its purpose.
In general, there is one routine described for each reference page.
However, in some cases it makes sense to describe more than one on the same
page if the routines are related. When this occurs, this section lists the
names of all the routines.
Synopsis
This section shows the function prototype. This book assumes that you
understand how to interpret the function prototype and how to write an
appropriate call for a specific interface.
Arguments
This section provides descriptions for the arguments associated with a
given routine. In most cases, argument descriptions begin with the word
specifies to indicate that you pass the argument (with some specified
value) to the routine. If the type of the argument appears as a void *, the
argument description states that you must define the type.
Description
This section contains explanations of the tasks performed by the routine.
Return Values
This section describes the return values that a given routine can return.
In most cases, if the routine returns an error value, this value is
described in the Return Values section.
Errors
This section provides the possible error constants a given routine can
return, along with a description of the error.
Example
This section provides the section where you can find an example of the
routine's use.
See Also
This section lists related routines, kernel interfaces, structures, system
calls, and so forth.
