\\brief deprecated context management functions of the low-level CUDA driver API (\fBcuda.h\fP)
.PP
This section describes the deprecated context management functions of the low-level CUDA driver application programming interface.

Note that this function is deprecated and should not be used.
.PP
Increments the usage count of the context and passes back a context handle in \fC*pctx\fP that must be passed to \fBcuCtxDetach()\fP when the application is done with the context. \fBcuCtxAttach()\fP fails if there is no context current to the thread.
.PP
Currently, the \fCflags\fP parameter must be 0.
.PP
\fBParameters:\fP
.RS 4
\fIpctx\fP - Returned context handle of the current context

\fIflags\fP - Context attach flags (must be 0)

.PP
Decrements the usage count of the context \fCctx\fP, and destroys the context if the usage count goes to 0. The context must be a handle that was passed back by \fBcuCtxCreate()\fP or \fBcuCtxAttach()\fP, and must be current to the calling thread.
