Function Documentation

_exit_tx()

PICOTM_NOTHROW PICOTM_NORETURN void _exit_tx

(

int

status

)

A transaction-safe implementation of _exit().

Bug:

Calling _exit() simply terminates the process. It probably should not be available in a transaction.

chdir_tx()

PICOTM_NOTHROW int chdir_tx

(

const char *

path

)

A transaction-safe implementation of chdir().

close_tx()

PICOTM_NOTHROW int close_tx

(

int

fildes

)

A transaction-safe implementation of close().

dup2_tx()

PICOTM_NOTHROW int dup2_tx	(	int	fildes,
		int	fildes2
	)

A transaction-safe implementation of dup2().

dup_tx()

PICOTM_NOTHROW int dup_tx

(

int

fildes

)

A transaction-safe implementation of dup().

fchdir_tx()

PICOTM_NOTHROW int fchdir_tx

(

int

fildes

)

A transaction-safe implementation of fchdir().

fsync_tx()

PICOTM_NOTHROW int fsync_tx

(

int

fildes

)

A transaction-safe implementation of fsync().

getcwd_tx()

PICOTM_NOTHROW char* getcwd_tx	(	char *	buf,
		size_t	size
	)

A transaction-safe implementation of getcwd().

link_tx()

PICOTM_NOTHROW int link_tx	(	const char *	path1,
		const char *	path2
	)

A transaction-safe implementation of link().

lseek_tx()

PICOTM_NOTHROW off_t lseek_tx	(	int	fildes,
		off_t	offset,
		int	whence
	)

A transaction-safe implementation of lseek().

mkdtemp_tx()

PICOTM_EXPORT char* mkdtemp_tx

(

char *

template

)

A transaction-safe implementation of mkdtemp() on Darwin system.

pipe_tx()

PICOTM_NOTHROW int pipe_tx

(

int

fildes[2]

)

A transaction-safe implementation of pipe().

pread_tx()

PICOTM_NOTHROW ssize_t pread_tx	(	int	fildes,
		void *	buf,
		size_t	nbyte,
		off_t	offset
	)

A transaction-safe implementation of pread().

pwrite_tx()

PICOTM_NOTHROW ssize_t pwrite_tx	(	int	fildes,
		const void *	buf,
		size_t	nbyte,
		off_t	offset
	)

A transaction-safe implementation of pwrite().

read_tx()

PICOTM_NOTHROW ssize_t read_tx	(	int	fildes,
		void *	buf,
		size_t	nbyte
	)

A transaction-safe implementation of read().

sleep_tx()

PICOTM_NOTHROW unsigned sleep_tx

(

unsigned

seconds

)

A transaction-safe implementation of sleep().

sync_tx()

PICOTM_NOTHROW void sync_tx

(

void

)

A transaction-safe implementation of sync().

unlink_tx()

PICOTM_NOTHROW int unlink_tx

(

const char *

path

)

A transaction-safe implementation of unlink().

write_tx()

PICOTM_NOTHROW ssize_t write_tx	(	int	fildes,
		const void *	buf,
		size_t	nbyte
	)

A transaction-safe implementation of write().
