时间：2025-03-02 13:07:32

#import "substrate.h"

static FILE * (*s_orig_fopen) ( const char * filename, const char * mode );

static FILE * my_fopen ( const char * filename, const char * mode ){

    return s_orig_fopen(filename, mode);

}

static void entry(void)  __attribute__ ((constructor));

static void entry(void) {

    MSHookFunction(fopen, my_fopen, &s_orig_fopen);

}

OR

#import "substrate.h"

static FILE * (*s_orig_fopen) ( const char * filename, const char * mode );

static FILE * my_fopen ( const char * filename, const char * mode ){

    return s_orig_fopen(filename, mode);

}

%ctor {

    MSHookFunction(fopen, my_fopen, &s_orig_fopen);

}
