Function Documentation

int _fstat_r	(	struct _reent *	r,
		int	fd,
		struct stat *	st
	)

Todo:

Handle file size with fstat

Definition at line 347 of file newlib-syscalls.c.

References NULL.

pid_t _getpid

(

void

)

Todo:

Return some process identifier on getpid()

Definition at line 115 of file newlib-syscalls.c.

void* _sbrk_r	(	struct _reent *	r,
		ptrdiff_t	increment
	)

Move the program break.

This function can increase the size of the allocated memory.

NEVER call this from ISRs (or anything that may call this function, e.g. malloc, free).
