PetscError

 Routine that is called when an error has been detected, usually called through the macro SETERRQ().

Synopsis

#include "petsc.h" 
int PetscError(int line,char *func,char* file,char *dir,int n,int p,char *mess,...)
Not Collective

Input Parameters

line - the line number of the error (indicated by __LINE__)
func - the function where the error occured (indicated by __FUNCT__)
dir - the directory of file (indicated by __SDIR__)
file - the file in which the error was detected (indicated by __FILE__)
mess - an error text string, usually just printed to the screen
n - the generic error number
p - 1 indicates the error was initially detected, 0 indicates this is a traceback from a previously detected error
mess - formatted message string - aka printf

Notes

Most users need not directly use this routine and the error handlers, but can instead use the simplified interface SETERRQ, which has the calling sequence 
    SETERRQ(n,mess)

Experienced users can set the error handler with PetscPushErrorHandler().
