__solve_symlinks

Syntax

#include <libc/symlink.h> int __solve_symlinks(const char *symlink_path, char *real_path);

Description

This function fully resolves given symlink in symlink_path---all path components and all symlink levels are resolved. The returned path in real_path is guaranteed to be symlink-clean and understandable by DOS. If symlink_path does not contain symlinks at all, it is simply copied to real_path.

real_path should be of size FILENAME_MAX, to contain the maximum possible length of path.

Return Value

Zero in case of error (and errno set to the appropriate error code), non-zero in case of success.

Portability

ANSI/ISO C	No
POSIX	No

Example

#include <libc/symlink.h> #include <stdio.h> const char fn[] = "c:/somedir/somelink"; char file_name[FILENAME_MAX]; __solve_symlinks(fn, file_name); printf("File %s is really %s\n", fn, file_name);
