which provide some convenient ways to print an SBValue object. Use that in TestValueAPI.py to print the 'days_of_week' char* array variable. For an example: cvf = lldbutil.ChildVisitingFormatter(indent=2) print cvf.format(days_of_week) produces: (const char *[7]) days_of_week = 0x00000001026a5060 (location) (const char *) [0] = "Sunday" (const char *) [1] = "Monday" (const char *) [2] = "Tuesday" (const char *) [3] = "Wednesday" (const char *) [4] = "Thursday" (const char *) [5] = "Friday" (const char *) [6] = "Saturday" llvm-svn: 135736
