PETSc version 3.15.5
PCHPDDMGetSTShareSubKSP
Gets whether the KSP in SLEPc ST and the fine-level subdomain solver is shared. 
Synopsis
#include "petscpc.h" 
PetscErrorCode PCHPDDMGetSTShareSubKSP(PC pc, PetscBool *share)
Input Parameter
|  | pc | - preconditioner context | 
Output Parameter
|  | share | - whether the KSP is shared or not | 
Notes
This is not the same as PCGetReusePreconditioner(). The return value is unlikely to be true, but when it is, a symbolic factorization can be skipped
when using a subdomain PCType such as PCLU or PCCHOLESKY.
