Function Documentation

void gan_assert ( Gan_Bool expr,
const char * message
)

| | Macro: Applies test and aborts program on false result with a message. Parameters: expr The test expression to be evaluated message The message printed when the test fails **Returns:**No value.Evaluates a test expression and aborts the program if the expression expr evaluates as false, printing the given error message. Ignored if NDEBUG is defined. | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

const char * gan_type_string ( Gan_Type type )

| | Generates a string identifier for an internal type. Parameters: **Returns:**String identifier, e.g. "8-bit", or "" for unknown format. | | --------------------------------------------------------------------------------------------------------------------------------------------- |
