If a \fBcontext\fP is passed, it is the application\(aqs responsibility to ensure \fBcontext\fP remains valid for the lifetime of the pool. .SH PARAMETERS .INDENT 0.0 .IP \(bu 2 \fBpool\fP: A \fBmongoc_client_pool_t\fP\&. .IP \(bu 2 \fBcallbacks\fP: A \fBmongoc_apm_callbacks_t\fP\&. .IP \(bu 2 \fBcontext\fP: Optional pointer to include with each event notification. .UNINDENT .SH RETURNS .sp Returns true on success. If any arguments are invalid, returns false and logs an error. .SH THREAD SAFETY .sp This function can only be called once on a pool, and must be called before the first call to \fBmongoc_client_pool_pop\fP\&. .SH SEE ALSO .sp Introduction to Application Performance Monitoring .SH AUTHOR MongoDB, Inc .SH COPYRIGHT 2017-present, MongoDB, Inc .\" Generated by docutils manpage writer. .
