evmeventnamematch
EvmEventNameMatch(3) Library Functions Manual EvmEventNameMatch(3) NAME
EvmEventNameMatch(), EvmEventNameMatchStr() - match EVM event name SYNOPSIS
Library EVM Support Library Parameters pattern The event name pattern sought. The pattern may be any valid event name string. It may include wildcard characters 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 DESCRIPTION
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 sup- plied pattern, 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. RETURN VALUE
The operation completed without error. The comparison was successful. The value of the match operand indicates whether the name matches the pattern. One of the arguments to the function is invalid. The supplied pattern contains invalid characters. The supplied event does not contain a name. ERRORS
The value of is not set. SEE ALSO
