ms_doy2md - Convert between day of year and month and day of month
#include <libmseed.h> int ms_doy2md ( int year, int jday, int *month, int *mday ); int ms_md2doy ( int year, int month, int mday, int *jday );
ms_doy2md calculates the month and day of month (mday) for a given year and day of year (jday).
ms_md2doy calculates the day of year (jday) for a given year, month and day of month (mday).
For both routines the expected and resulting ranges for each value are:
year : 1900 - 2100 jday : 1 - 366 month : 1 - 12 mday : 1 - 31
A day of year of 366 corresponds to the last day of a leap year.
ms_doy2md returns 0 on success and -1 on error.
ms_md2doy returns 0 on success and -1 on error.
