C API Reference -- Ns_GetRequest

### Ns_GetRequest

#### Overview

Return the parameters of a request

#### Syntax

        typedef void *Ns_OpContext;
        typedef int (Ns_OpProc) (void *context, Ns_Conn *conn);
        typedef void (Ns_OpDeleteProc) (void *context);

        void Ns_GetRequest(
        char *hServer
        char *method,
        char *URL,
        Ns_OpProc **pProc,
        Ns_OpDeleteProc **pDeleteProc,
        Ns_OpContext **pContext
        int *pflags
        );

#### Description

The Ns_GetRequest function sets`pproc` to the procedure the server would call to handle a request of method and URL on the specified server.`pContext` is set to the context that would be passed to `pProc` when called, and`pDeletepProc` is set to the delete procedure that would be called if `pProc` were unregistered (or re-registered). `pflags` points to the flags argument passed to Ns_RegisterRequest. The function returned is the best matching function and not necessarily an exact matching function.

You can use Ns_GetRequest and the NS_OP_NODELETE flag for Ns_RegisterRequest to implement wrapper-type operation, where you save the operation function, delete procedure, and context and register a new function that does some type of pre-processing before calling the operation or delete procedures.
