EVM Support Library
pattern The event name pattern sought. The pattern may be any
valid event name string. It may include wildcard charac‐
ters in place of any component.
event The event containing the event name to be compared
against the pattern.
match The result of the match. This operand is set to if the
name matches the pattern, and to if it does not.
candidate A character string to be matched against the pattern
Because special matching rules apply when deciding whether a candidate
event name matches a known name, the EVM name matching functions should
be used for matching purposes, rather than the C string comparison
functions The EVM functions match an event name against a supplied pat‐
tern, ignoring any trailing appended components in the candidate name,
and correctly matching wildcard characters.
The function takes an event and an event name pattern as input, and
returns an indication of whether the event contains a name which
matches the pattern in the match output argument. The pattern may be
any valid event name string, and may also include wildcard characters
in place of any component. A wildcard in the pattern matches zero or
more name components. A matches exactly one component. A match occurs
if the event name matches all components indicated by the pattern, even
if the name has additional trailing elements.
The function performs the same check as but takes a character string as
the candidate event name, instead of extracting the candidate event
name from a supplied event.
Both functions set the match output argument to if the name matches the
pattern, and to if it does not.
The operation completed without error. The comparison was successful.
The value of the match operand indicates whether the name matches the
One of the arguments to the function is invalid.
The supplied pattern contains invalid characters.
The supplied event does not contain a name.
The value of is not set.
