Creating Contexts
=================
- Function: GpgmeError gpgme_new (GpgmeCtx *CTX)
The function `gpgme_data_new' creates a new `GpgmeCtx' object and
returns a handle for it in CTX.
The function returns `GPGME_No_Error' if the context was
successfully created, `GPGME_Invalid_Value' if CTX is not a valid
pointer, and `GPGME_Out_Of_Core' if not enough memory is available.
