Dynamically calling implemented Functions

[AgentSmithers]

typedef struct
{
char *at_cmdName;
int8_t at_cmdLen;

at_funcationType at_custom_cmd[] = {

{"+TESC", 5, NULL, NULL, NULL, myTest3}, / / ​​Get the connected WiFi name password. has a problem

Hi Everyone,
I am reviewing a few ideas on how to dynamically call functions if they exist (I add and remove headers in my projects) and am currently leveraging ifdef directives. However, depending on how the includes are arraigned
some defines can be skipped by mistake. After review, it seems AT Firmware deploys a simular schema to dynamically add additional calls during runtime. Does anyone have a simple snippet of code in this context? I would like to implement this idea but there are some core parts I feel I would like some assistant/ideas on like a sample function to dynamically add to the growing structure. Has anyone implemented a function Schema like this?
