dlopen() and RTLD_* flags
=================================
-<dlfcn.h> declares
+<dlfcn.h> originally declares
enum { RTLD_NOW=0, RTLD_LAZY=1, RTLD_LOCAL=0, RTLD_GLOBAL=2, RTLD_NOLOAD=4}; // 32-bit
enum { RTLD_NOW=2, RTLD_LAZY=1, RTLD_LOCAL=0, RTLD_GLOBAL=0x00100, RTLD_NOLOAD=4}; // 64-bit
These differs from glibc ones in that
-1. They are not preprocessor #define:s so cannot be checked for with #ifdef RTLD_GLOBAL (dln.c in ruby does this)
+1. They are not preprocessor #define:s so cannot be checked for with `#ifdef RTLD_GLOBAL`. Termux patches this to
+ #define values for compatibility with several packages.
2. They differ in value from glibc ones, so cannot be hardcoded in files (DLFCN.py in python does this)
-3. They are missing some values (RTLD_BINDING_MASK, RTLD_NOLOAD, ...)
+3. They are missing some values (`RTLD_BINDING_MASK`, `RTLD_NOLOAD`, ...)
