Revision 1.7, Thu Jan 7 14:37:51 2016 UTC (8 years, 4 months ago) by mestre
ANSIfy trek(6) Note: Binary change is introduced due to function schedule() where its args are (int,double,char,char,char), but on trek.h are (int,double,int,int,int). Changed to the latter since the 3 last args are coordinates. OK tb@ |
