The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

|
* This file should be included as
|
|
* #include <KHR/khrplatform.h>
|
|
* by Khronos client API header files that use its types and defines.
|
|
*
|
|
* The types in khrplatform.h should only be used to define API-specific types.
|
|
*
|
|
* Types defined in khrplatform.h:
|
|
* khronos_int8_t signed 8 bit
|
|
* khronos_uint8_t unsigned 8 bit
|
|
* khronos_int16_t signed 16 bit
|
|
* khronos_uint16_t unsigned 16 bit
|
|
* khronos_int32_t signed 32 bit
|
|
* khronos_uint32_t unsigned 32 bit
|
|
* khronos_int64_t signed 64 bit
|
|
* khronos_uint64_t unsigned 64 bit
|
|
* khronos_intptr_t signed same number of bits as a pointer
|
|
* khronos_uintptr_t unsigned same number of bits as a pointer
|
|
* khronos_ssize_t signed size
|
|
* khronos_usize_t unsigned size
|
|
* khronos_float_t signed 32 bit floating point
|
|
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
|
|
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
|
|
* nanoseconds
|
|
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
|
|
* khronos_boolean_enum_t enumerated boolean type. This should
|
|
* only be used as a base type when a client API's boolean type is
|
|
* an enum. Client APIs which use an integer or other type for
|
|
* booleans cannot use this as the base type for their boolean.
|
|
*
|
|
* Tokens defined in khrplatform.h:
|
|
*
|
|
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
|
|
*
|
|
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
|
|
* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
|
|
*
|
|
* Calling convention macros defined in this file:
|
|
* KHRONOS_APICALL
|
|
* KHRONOS_APIENTRY
|
|
* KHRONOS_APIATTRIBUTES
|
|
*
|
|
* These may be used in function prototypes as:
|
|
*
|
|
* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
|
|
* int arg1,
|
|
