Hello, If i write a function in assembly and name it with prefix _? , ( example _?FUNCNAME ) will this make that function automatically reentrant. Or is it just a naming convention used by Keil if you write your function in C (and use the "reentrant" keyword). Regards, KC
From the point of view of your assembly code, it's just a naming convention. From the point of view of C code calling hat routine, it makes a statement about where its arguments are passed, and how to call it. I.e. if you have a currently working assembly routine called FOO or _FOO at the moment, and rename it to _?FOO, it's almost guaranteed to stop working.
"will this make that function automatically reentrant" Nothing is automatic in assembler! That's the whole point of assembler - you are in complete control of every detail; if you want anything done, you must do it all yourself. Assembler does precisely what you say - nothing more, nothing less.
