Name

linx_get_descriptor() - Get the socket descriptor associated with a LINX endpoint

Synopsis

#include <linx_types.h>
#include <linx.h>

int linx_get_descriptor(LINX *linx);

Description

The linx_get_descriptor() call returns the socket descriptor associated with a LINX endpoint. This socket descriptor is usually not needed when using the LINX API.

The LINX socket descriptor must be used if the application wants to use the generic select(2) or poll(2) calls. The application can then use LINX API function calls with the corresponding LINX endpoint handle to take care of events reported for a LINX socket descriptor. Alternatively, the LINX socket interface can be used.

linx is the handle of the LINX endpoint for which the socket descriptor is retrieved.

Return Value

Returns a socket descriptor.

Bugs/Limitations

None.

Notes

A LINX socket descriptor retrieved by linx_get_descriptor(3) must NOT be closed by calling close(2) . Close the LINX endpoint instead using linx_close(3) .
