VolServ API
Integration
To integrate the VolServ API in a client application, the client
includes the header file vs_client.h in the source modules
that reference the VolServ API types and functions. The client
then links the program with the VolServ API library
libvsapi.a with the -lvsapi option for the cc or ld
commands.
The following five header files are delivered with the VolServ
API:
Before any command can be sent by the client program, the
VolServ API must by initialized with a call to
VS_Initialize. The routine VS_Initialize creates and
initializes the APIs required variables and creates a
communication link with VolServ. Before the client program
terminates, it calls the
VS_Terminate routine to allow the
VolServ API to clean up its processing.
For example:
Header Files Description
vs_client.h Includes the VolServ API header files needed
by the client.
vs_defs.h Includes the VolServ API definitions needed
for the parameter lists.
vs_types.h Includes the VolServ API types and
enumerations.
vs_globals.h Includes the VolServ API global variables that
are accessible to the client.
vs_proto.h Includes the prototypes for all VolServ API
functions.
