| 2 | * This file specifies the format of gmon.out files. It should have | |
| 3 | * as few external dependencies as possible as it is going to be | |
| 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. | |
