Compiler Option: -mt
Link with thread-safe runtime library
Syntax
`
-mt
`
Description
The `-mt` compiler option forces linking with thread-safe runtime library for multithreaded applications. The thread-safe version is always used automatically if the FreeBASIC built-in threading functions are used, so you only need to specify this option if using your own threading routines.
The intrinsic macro `__FB_MT__` is set to non-zero (-1) if the `-mt` option was specified, or whether one of the `Threadtcreate` or `ThreadCall` keywords is used more above in the source code. Otherwise, it is set to zero (0).
