PX_DATE2STRING(3)					     Library Functions Manual						 PX_DATE2STRING(3)

NAME
PX_date2string -- Convert paradox date into formated string SYNOPSIS
#include <paradox.h> char * PX_date2string(pxdoc_t *pxdoc, long date, const char *format) DESCRIPTION
Creates a string representation of a paradox date as specified in the parameter format. The date must be either retrieved with PX_get_data_long(3) after calling PX_get_record(3) or by simply using the long value in the pxval_t struct as returned by PX_retrieve_record(3). The function uses internally the PX_timestamp2string(3) function. The format string may contain all chars as docu- mented with PX_timestamp2string(3), though only those concerning the date will produce resonable results. RETURN VALUE
Returns pointer to string on success and NULL on failure. SEE ALSO
PX_timestamp2string(3), PX_time2string(3) AUTHOR
