Subject: | Inacurate declaration of '_dos_findfirst()'
|
Hello.
The function _dos_findfirst as declared in dos.h :
unsigned int _dos_findfirst(char* name, /* should be "const char*
name" */
unsigned int attr,
struct _find_t* result);
The problem is that in C++ I can't call this function with a "const char*" type
for the file name.
In C this is not a problem since the compiler can cast away constness
automatically.
In C++ this should be a compilation error.
DJGPP GNU C++ compiler compiled this, but printed warnings.
I think the declaration should change to "const char* name".
-- to prevent the above error.
-- to be compatible with other C functions that get read-only strings.
-- the reader of the header file can deduce that the parameter name is not
to be changed.
Eyal.
