59.Sh DESCRIPTION
60These convenience functions translate numeric constants used by the
61.Lb libpmc
62to
63.Vt "const char *"
64pointers to human readable representations of their arguments.
65.Pp
66Function
67.Fn pmc_name_of_capability
68translates a PMC capability flag given in argument
69.Fa pc
70to a human readable string.
71PMC capabilities are described in
72.Xr pmc 3 .
73.Pp
74Function
75.Fn pmc_name_of_class
76translates the PMC class value specified in argument
77.Fa pc
78to a human readable name.
79PMC classes are described in
80.Xr pmc 3 .
81.Pp
82Function
83.Fn pmc_name_of_cputype
84translates the CPU type value specified in argument
85.Fa ct
86to a human readable name.
87CPU types known to the library are described in
88.Xr pmc 3 .
89.Pp
90Function
91.Fn pmc_name_of_disposition
92translates the PMC row disposition specified in argument
93.Fa pd
94to a human readable name.
95PMC row dispositions are described in
96.Xr hwpmc 4 .
97.Pp
98Function
99.Fn pmc_name_of_event
100translates the PMC event number specified by argument
101.Fa pe
102to a string.
103PMC event names are documented in section
104.Sx EVENT SPECIFIERS
105of
106.Xr pmc 3 .
107.Pp
108Function
109.Fn pmc_name_of_mode
110translates the PMC mode specified by argument
111.Fa pm
112to a human readable string.
113PMC modes are described in
114.Xr pmc 3 .
115.Pp
116Function
117.Fn pmc_name_of_state
118translates the value of argument
119.Fa ps
120to a human readable name.
121.Sh IMPLEMENTATION NOTES
122The returned pointers point to static storage inside the PMC
123library and should not be freed by the caller.
124.Sh RETURN VALUES
125These functions return a non-NULL pointer on successful completion.
126In case of an error, a NULL pointer is returned and the global
127variable
128.Va errno
129is set to indicate the error.
130.Sh ERRORS
131A call to these functions may fail with the following errors:
132.Bl -tag -width Er
133.It Bq Er EINVAL
134The function argument specified an invalid value.
