MLOpenArgv()

Usage

• MLINK MLOpenArgv(MLENV env, char **argv0, char **argv1, long *errno) opens a MathLink connection taking parameters from an ##1 array.

Notes

• MLInitialize() must be called before MLOpenArgv().

• MLOpenArgv() scans for the following at successive locations starting at argv0 and going up to just before argv1:

"-linkconnect"	connect to an existing link (LinkConnect)
"-linkcreate"	create a link (LinkCreate)
"-linklaunch"	launch a child process (LinkLaunch)
"-linkname", "name"	the name to use in opening the link
"-linkprotocol", "protocol"	the link protocol to use (tcp, pipes, etc.)

• MLOpenArgv() is not sensitive to the case of argument names.

• MLOpenArgv() ignores argument names that it does not recognize.

• MLOpenArgv() is called automatically by the MLMain() function created by mprep and mcc.

• With a main program main(int argc, char *argv[]) typical usage is MLOpenArgv(env, argv, argv+argc, errno).

• Avoiding an explicit argc argument allows MLOpenArgv() to work independent of the size of an int.

• On some computer systems, giving 0 for argv0 and argv1 will cause arguments to be requested interactively, typically through a dialog box.

• See Section 2.13.14.
