#include "petscsys.h"   
PetscErrorCode  PetscStrreplace(MPI_Comm comm,const char aa[],char b[],size_t len)
Not Collective

Input Parameters

comm - MPI_Comm of processors that are processing the string
aa - the string to look in
b - the resulting copy of a with replaced strings (b can be the same as a)
len - the length of b


Replaces ${PETSC_ARCH},${PETSC_DIR},${PETSC_LIB_DIR},${DISPLAY}, ${HOMEDIRECTORY},${WORKINGDIRECTORY},${USERNAME}, ${HOSTNAME} with appropriate values as well as any environmental variables.

PETSC_LIB_DIR uses the environmental variable if it exists. PETSC_ARCH and PETSC_DIR use what PETSc was built with and do not use environmental variables.
