.TH PROF 1 .SH NAMEprof \- display profile data.SH SYNOPSIS.B prof[.B \-v] [.B \-a] [.B \-l] [.BI \- "low\fR [ \fB\-\fIhigh\fR ]"] [ file ].SH DESCRIPTION.I Profinterprets the file.I mon.outproduced by the.I monitorsubroutine.Under default modes,the symbol table in thenamed object file.I (a.outdefault)is read and correlated with the.I mon.outprofile file.For each external symbol, the percentageof time spent executing between that symboland the nextis printed (in decreasing order),together with the number of times that routine was calledand the number of milliseconds per call..PPIf the.B \-aoption is used,all symbols are reported rather thanjust external symbols.If the.B \-loptionis used,the output is listed bysymbol value rather thandecreasing percentage..PPIf the.B \-voption is used,all printing is suppressedand a graphic version of the profileis producedon the standard output for display by the.IR  plot (1)filters.The numbers.I lowand .I high,by default 0 and 100, cause a selectedpercentage of the profile to be plottedwith accordingly higher resolution..PPIn order for the number of calls to a routine to be tallied,the.B \-poption of.I ccmust have been given when the file containing theroutine was compiled.This option also arranges for the.I mon.outfile to be produced automatically..SH FILES.ta \w'mon.out  'umon.out	for profile.bra.out		for namelist.SH "SEE ALSO"monitor(3), profil(2), cc(1), plot(1).SH BUGSBeware of quantization errors.
