Function equalStringObjects

src/object.cpp:636–645

Equal string objects return 1 if the two objects are the same from the * point of view of a string comparison, otherwise 0 is returned. Note that * this function is faster then checking for (compareStringObject(a,b) == 0) * because it can perform some more optimization. */
