global — Global functions.

Functions

int pskc_global_init ()
void pskc_global_done ()
void (*pskc_log_func) ()
void pskc_global_log ()
void pskc_free ()

Description

The library is initialized using pskc_global_init() which is a thread-unsafe function that should be called when the code that needs the PSKC library functionality is initialized. When the application no longer needs to use the PSKC Library, it can call pskc_global_done() to release resources.

The pskc_free() function is used to de-allocate memory that was allocated by the library earlier and returned to the caller.

For debugging, you can implement a function of the pskc_log_func signature and call pskc_global_log() to make the library output some messages that may provide additional information.

Functions

pskc_global_init ()

int
pskc_global_init (void);

This function initializes the PSKC library. Every user of this library needs to call this function before using other functions. You should call pskc_global_done() when use of the PSKC library is no longer needed.

Returns

On success, PSKC_OK (zero) is returned, otherwise an error code is returned.


pskc_global_done ()

void
pskc_global_done (void);

This function deinitializes the PSKC library, which were initialized using pskc_global_init(). After calling this function, no other PSKC library function may be called except for to re-initialize the library using pskc_global_init().


pskc_log_func ()

void
(*pskc_log_func) (const char *msg);

Function prototype for the application to be able to log PSKC messages, see pskc_global_log().

Parameters

msg

message to be logged.

 

pskc_global_log ()

void
pskc_global_log (pskc_log_func log_func);

Enable global debug logging function. The function will be invoked by the library when it wishes to print various debug information.

pskc_log_func is of the form, void (*pskc_log_func) (const char *msg);

The application may use this to provide a debug mode with trace information for the user.

Parameters

log_func

new global pskc_log_func log function to use.

 

pskc_free ()

void
pskc_free (void *ptr);

Deallocates memory region by calling free(). If ptr is NULL no operation is performed.

This function is necessary on Windows, where different parts of the same application may use different memory heaps.

Parameters

ptr

memory region to deallocate, or NULL.
