While testing a RXMCD exit, implemented in Java and preconfigured for the Rexx instance, commands
trigger the exit, however the DLL information is not supplied, but empty (expecting
"BSF4ooRexx850.dll" as that is the library that contains the callback function). Also, trying it
with AddCommandEnvironment()-API would not supply the dll name.
The sequence is: a Java program loads and configures a Rexx instance,
setting a RXCMD exit
handler (implemented in Java) and a RexxRedirectingCommandHandler
(implemented in Java), the
callback functions are in the native DLL ("BSF4ooRexx850.dll"). Both
handlers get invoked, the
RXCMD exit handler does not get a dll name (it is empty).
In addition, the exit intercepts also commands to CMD, however the dll name is
empty as well.
rexxapi.pdf says among other things:
Example 1.43. API — Rexx_IO_Exit parameter list
typedef struct {
struct { /* Condition flags */
unsigned rxfcfail : 1; /* Command failed. Trap with */
/* CALL or SIGNAL on FAILURE. */
unsigned rxfcerr : 1; /* Command ERROR occurred. */
/* Trap with CALL or SIGNAL on */
/* ERROR. */
} rxcmd_flags;
const char * rxcmd_address; /* Pointer to address name. */
unsigned short rxcmd_addressl; /* Length of address name. */
*const char * rxcmd_dll; /* dll name for command. */****unsigned short
rxcmd_dll_len; /* Length of dll name. 0 ==> */****/* executable file. */*
CONSTRXSTRING rxcmd_command; /* The command string. */
RXSTRING rxcmd_retc; /* Pointer to return code */
/* buffer. User allocated. */
} RXCMDHST_PARM;
What does "Length of dll name. 0 ==> executable file" mean, when would that take effect? Is there
anything I need to/can do to get at the DLL-name in the exit?
