Functions

prelude_init ()

int
prelude_init (int *argc,
              char **argv);

Call this function before using any other Prelude functions in your applications. It will initialize everything needed to operate the library and parses some standard command line options. argc and argv are adjusted accordingly so your own code will never see those standard arguments.

Parameters

argc

Address of the argc parameter of your main() function.

 

argv

Address of the argv parameter of your main() function.

 

Returns

0 on success, a negative value if an error occured.


prelude_deinit ()

void
prelude_deinit (void);

Call this function if you're done using the library and want to free global shared ressource allocated by libprelude.


prelude_check_version ()

const char *
prelude_check_version (const char *req_version);

If req_version is NULL this function will return the version of the library. Otherwise, req_version will be compared to the current library version. If the library version is higher or equal, this function will return the current library version. Otherwise, NULL is returned.

Parameters

req_version

The minimum acceptable version number.

 

Returns

The current library version, or NULL if req_version doesn't match.

prelude_fork_parent ()

void
