4 | * included in many different programs. That is, minimize the | |
5 | * number of #include's. | |
6 | * | |
7 | * A gmon.out file consists of a header (defined by gmon_hdr) followed | |
8 | * by a sequence of records. Each record starts with a one-byte tag | |
9 | * identifying the type of records, followed by records specific data. | |
