* This file specifies the format of gmon.out files. It should have

|
|
* included in many different programs. That is, minimize the

|
|
* A gmon.out file consists of a header (defined by gmon_hdr) followed
|
|
* by a sequence of records. Each record starts with a one-byte tag
|
|
* identifying the type of records, followed by records specific data.
