tt_pattern_create(library call) tt_pattern_create(library call) NAME tt_pattern_create -- request a new pattern object SYNOPSIS #include <Tt/tt_c.h> Tt_pattern tt_pattern_create(void) DESCRIPTION The tt_pattern_create function requests a new pattern object. After receiving the pattern object, the application fills in the mes- sage pattern fields to indicate what type of messages the process wants to receive and then registers the pattern with the ToolTalk service. The application can supply multiple values for each attribute added to a pattern (although some attributes are set and can only have one value). The pattern attribute matches a message attribute if any of the values in the pattern match the value in the message. If no value is specified for an attribute, the ToolTalk service assumes that any value will match. RETURN VALUE Upon successful completion, the tt_pattern_create function returns the opaque handle for a message pattern. The application can use this han- dle in future calls to identify the pattern object. The application can use tt_ptr_error(3) to extract one of the following Tt_status val- ues from the returned handle: TT_OK The operation completed successfully. TT_ERR_NOMP The ttsession(1) process is not running and the ToolTalk ser- vice cannot restart it. APPLICATION USAGE The application should use tt_free(3) to free any data stored in the address returned by the ToolTalk API. SEE ALSO Tt/tt_c.h - Tttt_c(5), tt_pattern_register(3), tt_ptr_error(3), tt_free(3). tt_pattern_create(library call)
