Tuxedo Vuser Functions (LRT)
Tuxedo Vuser functions begin with an lrt prefix. In addition to the lrt prefix, many Tuxedo Vuser functions have additional prefixes, such as tp, tx, or F. A tp prefix indicates a Tuxedo client action such as lrt_tpsend. A tx prefix indicates a global action such as lrt_tx_begin. An f prefix indicates that the function is related to the FML (Field Manipulation Language) buffer, such as lrt_Finitialize. Functions without a prefix simulate standard C functions, such as lrt_strcpy and lrt_memcpy. Some of the FML buffer functions have an optional "32" in the function name. These are the FML32 versions of the functions.
