Function Documentation

ea_checked_strdup()

char* ea_checked_strdup

(

const char *

string

)

Wrapper for strdup() that checks the result for a null-pointer.

ea_checked_strndup()

char* ea_checked_strndup	(	const char *	string,
		size_t	n
	)

Wrapper for strndup() that checks the result for a null-pointer.

ea_memdup()

void* ea_memdup	(	void *	data,
		size_t	size
	)

Create a copy of an arbitrary memory buffer. This is essentially a strdup() for non-string data.

Parameters

[in]	data	pointer to the bytes to copy
[in]	size	count of bytes to copy

Returns

freshly malloc'ed buffer containing a copy of the bytes, must be free'd by the caller

ea_read_check()

int ea_read_check	(	int	fd,
		char *	buf,
		size_t	len
	)

Read while ensuring and retrying until len is read or error occured.

ea_write_check()

int ea_write_check	(	int	fd,
		char *	buf,
		size_t	len
	)

Write while ensuring and retrying until len is written or error occured.

print_stat()

void print_stat

(

struct stat

sb

)

Print a detailed summary for the stat system call.
