15 This function can be called at any time to get the revision level of
16 the library. The version is encoded into an unsigned integer and
17 returned in the version argument. A revision number is composed of two
18 fields: a major number and a minor number. Both can be extracted from
19 the returned argument using macros provided in the header file:
20
21 PFMLIB_MAJ_VERSION(v)
22 returns the major number encoded in v.
23
24 PFMLIB_MIN_VERSION(v)
25 returns the minor number encoded in v.
26
28 The function returns whether or not it was successful. A return value
29 of PFMLIB_SUCCESS indicates success, otherwise the value is the error
30 code.
31
33 PFMLIB_ERR_INVAL
34 the argument is invalid, most likely a NULL pointer.
