Stability Interfaces Defined for USDT Providers

USDT providers require that stabilities be defined for the following five interface groups that fully specify a DTrace probe:

• Provider

• Modules

• Functions

• Probes

• Arguments

This will generally be done in the D program file where the provider is declared with pragmas using the triplets discussed in Stability Interface Attributes. For example:

#pragma D attributes Evolving/Evolving/Common provider providername provider
#pragma D attributes Private/Private/Common provider providername module
#pragma D attributes Private/Private/Common provider providername function
#pragma D attributes Evolving/Evolving/Common provider providername name
#pragma D attributes Evolving/Evolving/Common provider providername args
