c++ - Mix C-string and fortran-string in one file -

-

i have 1 question mixing c-string , fortran-string in 1 file.

supposed playing name string fixed length 9, define length macro 

#define name_len 9

in .c file.

there existing fortran-function, let's name fortran_function(char* name)

now have call fortran function in c function, let's name 

c_function(char name[]) {     fortran_function(name)  }

now problem is, how should declare c_function signature?

c_function(char name[]) c_function(char name[name_len +1])

or

c_function(char name[name_len])

under situations, should use 9 name length or 10?

my understanding that, long passed null-terminated string 9 characters c_function, declaration correct. right?

any other concern should put here? potential bugs?

there's 1 more gotcha here, if remember correctly. fortran not use null-terminated strings; instead, pads right end of buffer 0x20 (space). so, if have access fortran source, modify function signature take length of passed-in string argument. otherwise, crash fortran side of code.
