px_timestamp2string

PX_TIMESTAMP2STRING(3)					     Library Functions Manual					    PX_TIMESTAMP2STRING(3)

NAME

       PX_timestamp2string -- Convert paradox timestamp into formated string

SYNOPSIS

       #include <paradox.h>

       char * PX_timestamp2string(pxdoc_t *pxdoc, double timestamp, const char *format)

DESCRIPTION

       Creates	a  string representation of a paradox timestamp as specified in the parameter format.  The timestamp must be either retrieved with
       PX_get_data_double(3) after calling PX_get_record(3)  or  by  simply  using  the  double  value	in  the  pxval_t  struct  as  returned	by
       PX_retrieve_record(3). A timestamp contains both time and date information. The format string contains chars which stand for certain values
       of the date/time. The following table lists all available characters with a meaning. All other characters are being  copied  unmodified	to
       the output string. If a special character shall not be interpreted it must be preceded with a backslash.
