* Purpose
* =======
*
* PB_Cconjg conjugates of the scalar alpha.
*
* Arguments
* =========
*
* TYPE (local input) pointer to a PBTYP_T structure
* On entry, TYPE is a pointer to a structure of type PBTYP_T,
* that contains type information (See pblas.h).
*
* ALPHA (local input) pointer to CHAR
* On entry, ALPHA specifies the scalar alpha.
*
* CALPHA (local output) pointer to CHAR
* On exit, CALPHA contains the conjugate of the scalar alpha.
