Linux Man Page Viewer
The following form allows you to view linux man pages.
int pfm_get_version(unsigned int *version);
This function can be called at any time to get the revision level of
the library. The version is encoded into an unsigned integer and
returned in the version argument. A revision number is composed of two
fields: a major number and a minor number. Both can be extracted from
the returned argument using macros provided in the header file:
returns the major number encoded in v.
returns the minor number encoded in v.
The function returns whether or not it was successful. A return value
of PFMLIB_SUCCESS indicates success, otherwise the value is the error
the argument is invalid, most likely a NULL pointer.
