symdl is a simple little tool, its function is very similar to dlsym, with symdl, you can pass any global C function name string or global variable, so as to achieve the dynamic call of C function or access the global variable.
#import <symdl/symdl.h>
#import <stdio.h>
int MyIntGlobalVar = 10;
int main(){
FILE *(*my_fopne)(char *, char*) = symdl("fopen");
FILE *fp = my_fopne("your path","w+");
//do something
int *MyIntGlobalVarPtr = (int *)symdl("MyIntGlobalVar");
printf("MyIntGlobalVar: %d\n", *MyIntGlobalVarPtr);
return 0;
}
