Function Documentation

fid_sscanf()

static int fid_sscanf ( const char *  s, struct m0_fid *  fid, int *  nob  )

static

Parses fid string representation.

Three formats are supported:

* CONT:KEY, where CONT and KEY are in sexadecimal.
* <CONT:KEY>, where CONT and KEY are in sexadecimal.

* TYPE|CONT:KEY, where TYPE is a 1-character fid type
  (m0_fid_type::ft_id), CONT is the container sans type and KEY is the
  key (key and container are in %*i format: decimal by default,
  sexadecimal when start with 0x, octal when start with 0).
