NAME
ggidev-inc_3, ggidev-dec_3, ggidev-negate_3, ggidev-abs_3 - Unary arithmetic triple-int operationsSYNOPSIS
#include <ggi/internal/triple-int.h> unsigned *inc_3(unsigned x[3]); unsigned *dec_3(unsigned x[3]); unsigned *negate_3(unsigned x[3]); unsigned *abs_3(unsigned x[3]);
DESCRIPTION
inc_3 increments x by one. Equivalent to ++x.dec_3 decrements x by one. Equivalent to --x.
negate_3 negates x. Equivalent to x=-x.
abs_3 takes the absolute value of x. Equivalent to x=x<0?-x:x.
RETURN VALUE
inc_3, dec_3, negate_3 and abs_3 all return a pointer to x which has been updated in place.EXAMPLES
Some unary arithmetic operations on triple-ints:unsigned x[3]; assign_int_3(x, 44); negate_3(x); /* x is now -44 */ inc_3(x); /* x is now -43 */ abs_3(x); /* x is now 43 */ dec_3(x); /* x is now 42 */
