NAME

function_profile() - get function profiling information for an object

SYNOPSIS

mixed *function_profile( object ob );

DESCRIPTION

Returns  function  profiling  information for 'ob', or this_object() if
'ob' is not specified.  This is only available if the driver  was  com‐
piled with PROFILE_FUNCTIONS defined.

RETURN VALUE

An  array  of  mappings is returned, one for each function in 'ob', the
format of the mapping is:
([ "name"     : name_of_the_function,
"calls"    : number_of_calls,

/* cpu time expressed in microseconds */
"self"     : cpu_time_spent_in self,
"children" : cpu_time_spent_in_children
])
The usefulness of this is tied to the resolution of the CPU clock--even
though  the  units  are microseconds, the CPU timer resolution is often
much less
