Define Documentation

#define BL_IGNORE_MAX   100000

BL is a macro that expands to the literal value 100000.

It is defined when compiling either Fortran or C++ code; i.e. when either BL or BL is defined. It is used in calls to istream::ignore() in the BoxLib code when reading in characters from an istream. We use this macro instead of the more proper INT from <limits.h> since at least one compiler didn't work properly when istream::ignore() was passed INT.
