The scl_function pragma
The scl_function pragma allows the user to capture a function. All interfaces that STRIDE works with must be captured.
When captured for the purpose of interception (in which case the term intercept-able is used throught the documentation) optional arguments allow specification of how would it be done. The Instrument Build Tool will use those options to generate appropriate function interception code.
Syntax
#pragma scl_function(function-name [,context, name-mangling, group-id])
| Parameters | Type | Description |
| function-name | Identifier | Name of the function to capture. |
| context | String | Optional. Context in which the function is going to be intercepted. Possible values are "REFERENCE" - intercept at the function call (aka user) or "DEFINITION" - intercept at the function definition (aka owner). |
| name-mangling | String | Optional. Type of name mangling to be used when intercepted. Possible values are "EXPLICIT" or "IMPLICIT". |
| group-id | String | Optional. User defined identifier representing the group to which this function belongs when solving name mangling conflicts. |
Notes
- The function must be declared as a designator with external linkage.
- A compilation error is reported if an attempt is made to capture a function more than once (with either scl_func or scl_function).
Example
int foo(int x);
void boo(void);
#pragma scl_function(foo)
#pragma scl_function(boo, "DEFINITION", "IMPLICIT", "TEST_GROUP")
