PetscStrreplace#

Replaces substrings in string with other substrings

Synopsis#

#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

Notes#

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.
