Is there a way to use fopen_s() with GCC or at least create a #define about it?

Question

MSVC compiler says that fopen() is deprecated, and recommends the use of fopen_s().

Is there any way to use fopen_s() and stil

Answer 1

In C/C++ code,

#ifdef __unix
#define fopen_s(pFile,filename,mode) ((*(pFile))=fopen((filename),(mode)))==NULL
#endif

In Makefile

CFLAGS += -D'fopen_s(pFile,filename,mode)=((*(pFile))=fopen((filename),(mode)))==NULL'

Attention that on success fopen_s return 0 while fopen return a nonzero file pointer. Therefore it is necessary to add "==NULL" to the end of macro, e.g.:

if (fopen_s(&pFile,filename,"r")) perror("cannot open file");
