D_PATH(9) The Linux VFS D_PATH(9)

NAME

d_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.
