Dumping and Resetting Profile Information

The
_PGOPTI_Prof_Dump_And_Reset()
function dumps the profile information to a new .dyn file and then resets the dynamic profile counters. Then the execution of the instrumented application continues.
The prototype of the function call is listed below.
Syntax
void _PGOPTI_Prof_Dump_And_Reset(void);
This function is used in non-terminating applications and may be called more than once. Each call will dump the profile information to a new .dyn file.

Recommended Usage

Periodic calls to this function enables a non-terminating application to generate one or more profile information files (
.dyn
files). These files are merged during the feedback phase of profile-guided optimizations. The direct use of this function enables your application to control precisely when the profile information is generated.
