NAME

    prof - display profile data

SYNOPSIS

    prof [ -v ] [ -a ] [ -l ] [ -_l_o_w [ -_h_i_g_h ] ] [ file ]

DESCRIPTION

    _P_r_o_f interprets the file _m_o_n._o_u_t produced by the _m_o_n_i_t_o_r
    subroutine.  Under default modes, the symbol table in the
    named object file (_a._o_u_t default) is read and correlated
    with the _m_o_n._o_u_t profile file.  For each external symbol,
    the percentage of time spent executing between that symbol
    and the next is printed (in decreasing order), together with
    the number of times that routine was called and the number
    of milliseconds per call.

    If the -a option is used, all symbols are reported rather
    than just external symbols.  If the -l option is used, the
    output is listed by symbol value rather than decreasing per-
    centage.

    If the -v option is used, all printing is suppressed and a
    graphic version of the profile is produced on the standard
    output for display by the _p_l_o_t(1) filters.  The numbers _l_o_w
    and _h_i_g_h, by default 0 and 100, cause a selected percentage
    of the profile to be plotted with accordingly higher resolu-
    tion.

    In order for the number of calls to a routine to be tallied,
    the -p option of _c_c must have been given when the file con-
    taining the routine was compiled.  This option also arranges
    for the _m_o_n._o_u_t file to be produced automatically.
