Detailed Description
Implementation of realpath() that is portable on all our platforms.
Function Documentation
◆ Realpath()
| char * Realpath | ( | const char * | _path | ) |
Makes an absolute filename, resolving symbolic links etc.
- Parameters
-
_path Input path
- Returns
- real path, to be free()'d
POSIX 2004 states : If resolved_name is a null pointer, the behavior of realpath() is implementation-defined.
but POSIX 2008 : If resolved_name is a null pointer, the generated pathname shall be stored as a null-terminated string in a buffer allocated as if by a call to malloc().
So we assume all platforms now support passing NULL. If you find a platform where this is not the case, please add a new implementation with ifdef's.
