9: PetscIgnoreErrorHandler - Ignores the error, allows program to continue as if error did not occure
11: Not Collective
13: Input Parameters:
14: + line - the line number of the error (indicated by __LINE__)
15: . func - the function where error is detected (indicated by __FUNCT__)
16: . file - the file in which the error was detected (indicated by __FILE__)
17: . dir - the directory of the file (indicated by __SDIR__)
18: . mess - an error text string, usually just printed to the screen
19: . n - the generic error number
20: . p - specific error number
21: - ctx - error handler context
23: Level: developer
25: Notes:
26: Most users need not directly employ this routine and the other error
27: handlers, but can instead use the simplified interface SETERRQ, which has
28: the calling sequence
29: $ SETERRQ(number,p,mess)
31: Notes for experienced users:
32: Use PetscPushErrorHandler() to set the desired error handler. The
