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.
