HP-UX Event ManagerProgrammer's Guide

• EvmVarSet — Sets the value of a named variable data item in an event. This function is
used both for adding a variable and for altering the value of an existing variable. For more
information about this function, see EvmVarSet(3).
• EvmVarGet — Returns information of the specified event variable in a given variable
structure. The calling function must free any memory used by the variable by calling
EvmVarRelease(). For more information about this function, see EvmVarGet(3).
• EvmVarRelease — Releases memory that was allocated when the specified variable was
retrieved from an event by EvmVarGet(). However, it releases only heap storage referenced
by the structure. It does not release the specified variable structure. For more information
about this function, see EvmVarRelease(3).
