The ifx_var_getlen() function returns the length of the data in an lvarchar pointer or var binary host variable.

mint ifx_var_getlen(var_bin)

	var binary **var_bin;

mint ifx_var_getlen(lvar)

	lvarchar **lvar;

 



var_bin  

is the address of the var binary host variable whose length is returned. 


lvar

is the address of the lvarchar pointer host variable whose length is returned.

The length that the ifx_var_getlen() function returns is the number of bytes that have been allocated for the data buffer of the lvar or var_bin host variable.
