INFORMIX-ESQL/C Programmer's Manual ESQL/C Function Library

The ifx_var_dealloc() function deallocates the memory that was allocated for the data buffer of a var binary host variable.

mint ifx_var_dealloc(var_bin)

	var binary **var_bin;

mint ifx_var_dealloc(lar)

	lvarchar **lvar;

 



var_bin  

is the address of the var binary pointer host variable whose data buffer is deallocated. 


lvar

is the address of the lvarchar pointer host variable whose data buffer is allocated.

The allocation flag of the ifx_var_flag() function tells ESQL/C which allocation method to use for the data buffer. Regardless of whether ESQL/C (allocation flag set to 1) or your application (allocation flag set to 0) allocates the memory, you must explicitly deallocate memory that was allocated to an lvarchar or var binary host variable.
