Bug 3530

Summary: Sdl uses a function i have defined for its own purposes
Product: SDL Reporter: Kaden Thomas <thomas.kaden4>
Component: mainAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED INVALID QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: philipp.wiesemann, sezeroz

Description Kaden Thomas 2016-12-22 07:56:40 UTC 
in my main.c file i have this function:

void read(void *env, uint8_t data)
{
	printf("%p : 0x%x\n", env, data);
}

What I found is that if I call SDL_Init(), data is printed using my function unless I mark the function as static or static inline.
Comment 1 Philipp Wiesemann 2016-12-22 20:54:22 UTC 
read() is already available ("unistd.h", POSIX). The linking might get messed up if there are more functions with the same name (see also bug 2884).
Comment 2 Ozkan Sezer 2016-12-29 06:29:28 UTC 
man 2 read

This must be closed as invalid.

Yes, you generally can't reimplement C library functions in your own program. The behavior is undefined on various platforms.
