Detailed Description

Include file for SDL test framework.

This code is a part of the SDL2_test library, not the main SDL library.

Note: The fuzzer implementation uses a static instance of random context internally which makes it thread-UNsafe.

Function Documentation

void SDLTest_FuzzerInit ( Uint64  execKey)

Initializes the fuzzer for a test

/param execKey Execution "Key" that initializes the random number generator uniquely for the test.

int SDLTest_GetFuzzerInvocationCount ( )

Returns the invocation count for the fuzzer since last ...FuzzerInit.

char* SDLTest_RandomAsciiString ( )

Generates random null-terminated string. The minimum length for the string is 1 character, maximum length for the string is 255 characters and it can contain ASCII characters from 32 to 126.

Note: Returned string needs to be deallocated.

Returns
Newly allocated random string; or NULL if length was invalid or string could not be allocated.

Definition at line 478 of file SDL_test_fuzzer.c.

References SDLTest_RandomAsciiStringWithMaximumLength().

char* SDLTest_RandomAsciiStringOfSize ( int  size)

Generates random null-terminated string. The length for the string is defined by the size parameter. String can contain ASCII characters from 32 to 126.

Note: Returned string needs to be deallocated.

Parameters
sizeThe length of the generated string
Returns
Newly allocated random string; or NULL if size was invalid or string could not be allocated.

char* SDLTest_RandomAsciiStringWithMaximumLength ( int  maxLength)

Generates random null-terminated string. The maximum length for the string is defined by the maxLength parameter. String can contain ASCII characters from 32 to 126.

Note: Returned string needs to be deallocated.

Parameters
maxLengthThe maximum length of the generated string.
Returns
Newly allocated random string; or NULL if maxLength was invalid or string could not be allocated.
