]]> ]]> tt_pattern_xarg_add library call tt_pattern_xarg_add add a new argument with an interpreted XDR value to a pattern object #include <Tt/tt_c.h> Tt_status tt_pattern_xarg_add Tt_pattern m Tt_mode n const char *vtype xdrproc_t xdr_proc void *value The tt_pattern_xarg_add function adds a new argument with an interpreted XDR value to a pattern object. The m argument is the opaque handle for the pattern involved in this operation. The n argument specifies who (sender, handler, observers) writes and reads a pattern argument. The following modes are defined: TT_IN The argument is written by the sender and read by the handler and any observers. TT_OUT The argument is written by the handler and read by the sender and any reply observers. TT_INOUT The argument is written by the sender and the handler and read by all. The vtype argument describes the type of argument data being added. The xdr_proc argument points to the XDR procedure to be used to serialize the data pointed to by value. The value argument is the data to be serialized. Upon successful completion, the tt_pattern_xarg_add function returns the status of the operation as one of the following Tt_status values: TT_OK The operation completed successfully. TT_ERR_MODE The specified Tt_mode is invalid. TT_ERR_NOMP The &cdeman.ttsession; process is not running and the ToolTalk service cannot restart it. TT_ERR_POINTER The pointer passed does not point to an object of the correct type for this operation. TT_ERR_XDR The XDR procedure failed on the given data, or evaluated to a zero-length expression. &cdeman.Tt.tt.c.h;
