D_PATH(9) The Linux VFS D_PATH(9)NAMEd_path - return the path of a dentry
SYNOPSIS
char * d_path(const struct path * path, char * buf, int buflen);
ARGUMENTS
path
path to report
buf
buffer to return value in
buflen
buffer length
DESCRIPTION
Convert a dentry into an ASCII path name. If the entry has been deleted
the string “ (deleted)” is appended. Note that this is ambiguous.
Returns a pointer into the buffer or an error code if the path was too
long. Note: Callers should use the returned pointer, not the passed in
buffer, to use the name! The implementation often starts at an offset
into the buffer, and may leave 0 bytes at the start.
“buflen” should be positive.
