Language Conversion for RSC/MP Function Calls

B-2

Parameter Syntax

Table B-2 lists the C and COBOL parameter passing syntax.

String Termination

In the C programming language, the ends of character strings (character strings are

PIC X fields) are identified by a numeric 0 as the last character (called the NULL

terminator). To aid COBOL programmers, the RSC/MP API functions also recognize a

space at the end of the string as the end-of-string terminator. You must place blanks at

the end of all character strings to fill out the character strings passed to RSC/MP

functions. See the SERVER-NAME value in the COBOL example on page B-4.

COBOL Programs

UNIX COBOL programs prefix the function name with C_ to use the C calling

sequence.

Table B-2. C and COBOL Parameter Passing Syntax

C Parameter

Passing Syntax COBOL Parameter Passing Syntax Description

*name USING name BY REFERENCE The address of (or pointer to)

the variable.

VOID *

name USING name BY REFERENCE A pointer to a nonspecific

data type.

Note. In some Microsoft COBOL versions, programs must prefix the function name with an

underscore (_) instead of C_. Check your COBOL manual for more information.
