Parys()
From Lianjapedia
PURPOSE
Return a pointer to a currency string
SYNONYM
api_par_ys()
SYNOPSIS
#include "lianja_api.h" char *_parys(order [,index]) <input parameters> int order; /* Placement in actual parameter list */ int index; /* Array element index */ <output parameters> none
DESCRIPTION
The _parys() function gets a currency parameter and returns a character pointer. The order specifies the actual placement in the parameter list. If the parameter passed is an array, then the optional index value is used to specify the required element number.
NOTE: there is only one pointer on the stack for _parys(). The 'C' strcpy() function must be used to copy the result to a variable, you cannot simple pass the pointer.
EXAMPLE
The following example copies the first parameter passed to a string and then returns the result.
Example Lianja script:
m_currency=$23.8327 m_strcurr =currency_ctos( m_currency ) return
Example 'C' function:
#include "lianja_api.h" lianjaapi_currency_ctos() { char currency[32]; if (_parinfo(1) == API_YTYPE ) { strcpy( currency, _parys(1)); } else { strcpy( date, "" ); } _retc( currency ); }
