LIBRARY


.Lb libpmc

SYNOPSIS


.In pmc.h const char * pmc_name_of_capability enum pmc_caps pc const char * pmc_name_of_class enum pmc_class pc const char * pmc_name_of_cputype enum pmc_cputype ct const char * pmc_name_of_disposition enum pmc_disp pd const char * pmc_name_of_event enum pmc_event pe const char * pmc_name_of_mode enum pmc_mode pm const char * pmc_name_of_state enum pmc_state ps

DESCRIPTION

These convenience functions translate numeric constants used by the
.Lb libpmc to
.Vt const char * pointers to human readable representations of their arguments.

Function pmc_name_of_capability translates a PMC capability flag given in argument pc to a human readable string. PMC capabilities are described in pmc(3).

Function pmc_name_of_class translates the PMC class value specified in argument pc to a human readable name. PMC classes are described in pmc(3).

Function pmc_name_of_cputype translates the CPU type value specified in argument ct to a human readable name. CPU types known to the library are described in pmc(3).

Function pmc_name_of_disposition translates the PMC row disposition specified in argument pd to a human readable name. PMC row dispositions are described in hwpmc(4).

Function pmc_name_of_event translates the PMC event number specified by argument pe to a string. PMC event names are documented in section EVENT SPECIFIERS of pmc(3).

Function pmc_name_of_mode translates the PMC mode specified by argument pm to a human readable string. PMC modes are described in pmc(3).

Function pmc_name_of_state translates the value of argument ps to a human readable name.

IMPLEMENTATION NOTES

The returned pointers point to static storage inside the PMC library and should not be freed by the caller.

RETURN VALUES

These functions return a non-NULL pointer on successful completion. In case of an error, a NULL pointer is returned and the global variable errno is set to indicate the error.

ERRORS

A call to these functions may fail with the following errors:
[EINVAL]
  The function argument specified an invalid value.
