Typedef Documentation

typedef struct Ewl_Config_Cache Ewl_Config_Cache

The Ewl_Config_Cache structure

Function Documentation

void ewl_backtrace ( void )

This will print a backtrace at the given point.

Returns:: Returns no value.

int ewl_cast_pointer_to_integer ( void * ptr )

Parameters:

ptr,:

the pointer to cast

Returns:: The integer value of the pointer

This function casts a pointer into an integer. If there should be an information lost, i.e. the content of the pointer does not fit into an integer, it will print a runtime warning.

void ewl_print_warning ( void )

This is used by debugging macros for breakpoints.

Returns:: Returns no value.

Set a breakpoint at this function in order to retrieve backtraces from warning messages.

void ewl_segv ( void )

This will cause EWL to SEGV. (Handy for debugging).

Returns:: Returns no value.
