Function Documentation

MqInitGetArg0()

MQ_EXTERN MK_BFL libmqmsgque::MqInitGetArg0

(

void

)

get the process startup-prefix argument

Returns

a pointer to the initialization buffer (Only C-API)

Attention

if not set return a MK_NULL pointer

Reset the process-startup-prefix argument to an empty list …

The startup-prefix have to be the name of the executable, found in the PATH environment variable, and additional arguments like the script name or the required startup options. The startup-prefix is used for two different purpose:

• To start a new entity using the MqStartAs "--spawn" command-line option.
• To replace the command-line-argument "... @ SELF ..." with "... @ startup-prefix ..." at LinkCreate.

Every use of this function will free the data of the previous startup-prefix. By default the startup-prefix is set during application startup by ccmqmsgque and have not to be initialized again.

Example from server.cc → initialize the startup-prefix with the data read from service-args

      void INIT() {
	SendSTART   (); 
        MqMsgque::InitSetArg0 (MkBufferListC {ReadALL()});
	SendRETURN  (); 
      }

Here is the caller graph for this function:

MqInitSetArg0()

MQ_EXTERN void libmqmsgque::MqInitSetArg0

(

MK_BAC

bfl

)

set the process startup-prefix argument to bfl

The startup-prefix is the argument(s) required to start the application… this is minimal the binary-path for binaries (same as as used on command-line) or the interpreter+scriptFile for scripts.

Parameters

[in]

bfl

the object will be merged into the startup-prefix, afterwords the bfl is empty and can be deleted

Example

Initialize the application startup command in C

MqInitSetArg0(MkBufferListCreateV("myExec", "myExecArgument_1")); 

Here is the caller graph for this function:

MqInitSetArg0VA()

MQ_EXTERN void libmqmsgque::MqInitSetArg0VA	(	MK_STRN	arg0,
			... )

set the process startup-prefix to a args

Attention

… the C-Api requires a MK_NULL item on end to signal… end-of-list

MqInitSetArg0VAL()

MQ_EXTERN void libmqmsgque::MqInitSetArg0VAL	(	MK_STRN	arg0,
		va_list	var_list )

set the process startup-prefix to var_list

Here is the caller graph for this function:
