The Signal Converted to a Return Status routine converts any
    signaled condition value to a value returned as a function. The
    signaled condition is returned to the caller of the user routine
    that established the handler that is calling LIB$SIG_TO_RET. This
    routine may be established as or called from a condition handler.

1  –  Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2  –  Arguments

 signal-arguments

    OpenVMS usage:vector_longword_unsigned
    type:         unspecified
    access:       read only
    mechanism:    by reference, array reference

    Signal argument vector. The signal-arguments argument contains
    the address of an array that is this signal argument vector
    stack.

    See the HP OpenVMS Programming Concepts Manual for a description
    of the signal argument vector.

 mechanism-arguments

    OpenVMS usage:structure
    type:         unspecified
    access:       read only
    mechanism:    by reference

    Mechanism arguments vector. The mechanism-arguments argument
    contains the address of a structure that is this mechanism
    argument vector stack.

    See the HP OpenVMS Programming Concepts Manual for a description
    of the mechanism argument vector.
