The following tables provides a simple translation for different data types:
C Type |
ESL Type |
short |
small integer in function call |
long |
integer in function call |
long * |
reference integer in function call; integer in subroutine call |
float |
small float in function call |
double |
float in function call |
double * |
reference float in function call, float in subroutine call |
void * |
reference in function call without any type declaration |
char |
small string in function call |
HSTRING |
string in function call |
PHSTRING |
string in subroutine call |
struct in C |
structure in ESL with optional using clauses for each field |
Note. PHSTRING and HSTRING are both Esl defined string types, therefore will not be present in Operating System or Third Party supplied functions. Also, although unsigned long is not in this table, long is. In most cases long can be substituted for unsigned long without any problems. We will go into a more in depth discussion of this conversion later.
