Macro Definition Documentation

maug_bufcat

#define maug_bufcat	(		c,
			buf,
			buf_idx,
			buf_sz,
			cleanup )

Value:

   buf[buf_idx++] = c; \
   if( buf_idx >= buf_sz ) { goto cleanup; }

maug_bufpad

#define maug_bufpad	(		pad_c,
			pad_sz,
			i,
			buf,
			buf_idx,
			buf_sz,
			cleanup )

Value:

   i = 0; \
   while( i < pad_sz ) { \
      maug_bufcat( pad_c, buffer, buffer_idx, buffer_sz, cleanup ); \
      i++; \
   }

maug_hctoi

#define maug_hctoi

(

c

)

Value:

   ('9' > (c) ? (c) - '0' : 'a' > (c) ? 10 + (c) - 'A' : 10 + (c) - 'a')

Convert a single char hex digit to the int it represents.

maug_xtoa

#define maug_xtoa	(		num,
			base,
			rem,
			dest,
			dest_idx,
			digits,
			digits_done,
			pad )

Value:

   dest_idx += digits; \
   while( 0 != num ) { \
      /* Get the 1's place. */ \
      rem = num % base; \
      dest[--dest_idx] = (9 < rem) ? \
         /* > 10, so it's a letter. */ \
         (rem - 10) + 'a' : \
         /* < 10, so it's a number. */ \
         rem + '0'; \
      /* Move the next place value into range. */ \
      num /= base; \
      digits_done++; \
   } \
   while( digits_done < digits ) { \
      dest[--dest_idx] = '0'; \
      digits_done++; \
   }
