Macro Definition Documentation

CLK_DECL

#define CLK_DECL

(

n

)

Value:

clock_t clk_start[n], clk_end[n], clk_diff[n]; int clk_start_line[n], clk_stop_line[n]

CLK_DECL(n) declares an array of n clock_t to be used by CLK_* macros.

Must occur before any CLK_* macros call.

CLK_DUMP

#define CLK_DUMP

(

n

)

Value:

   do { \
   fprintf(stderr, "%s:%d->%d CLK[%d]= %.16f sec.\n", \
      __FILE__, clk_start_line[n], clk_stop_line[n], \
      n, (double) clk_diff[n] / (double) CLOCKS_PER_SEC);\
} while (0)

CLK_STA

#define CLK_STA

(

)

Value:

CLK_DECL(1); CLK_START(0)

Shortcuts for function profiling.

CLK_STA() must be at end of local declarations. CLK_STO() must be just before end of function.

CLK_START

#define CLK_START

(

n

)

Value:

do { clk_start_line[n] = __LINE__; clk_start[n] = clock(); } while (0)

CLK_START(n) starts clock n.

Must occur after CLK_DECL() and before CLK_STOP().

CLK_STO

#define CLK_STO

(

)

Value:

CLK_STOP(0); CLK_DUMP(0)

CLK_STOP

#define CLK_STOP

(

n

)

Value:

do { clk_end[n] = clock(); clk_diff[n] = clk_end[n] - clk_start[n]; clk_stop_line[n] = __LINE__; } while (0)
