typedef unsigned long fd_attribute

Function Documentation

__fd_close()

void __fd_close

(

int

fd

)

Unsets fd attributes

Parameters

[in]

fd

file descriptor

__file_needs_conversion()

int __file_needs_conversion

(

int

fd

)

Determines if file descriptor needs conversion from EBCDIC to ASCII. Call __file_needs_conversion_init first before calling this function.

Parameters

[in]

fd

file descriptor

Returns

returns 1 if file needs conversion, 0 if not.

__file_needs_conversion_init()

int __file_needs_conversion_init	(	const char *	name,
		int	fd
	)

Determines if file needs conversion from EBCDIC to ASCII.

Parameters

[in]	name	path to file
[in]	fd	file descriptor

Returns

returns 1 if file needs conversion, 0 if not.

__guess_ae()

int __guess_ae	(	const void *	src,
		size_t	size
	)

Guess if string is ASCII or EBCDIC.

Parameters

[in]	src	- character string.
[in]	size	- number of bytes to analyze.

Returns

guessed CCSID.

__guess_fd_ue()

int __guess_fd_ue	(	int	fd,
		char *	errmsg,
		size_t	er_size,
		int	is_new_fd
	)

Guess if string is UTF8 (ASCII) or EBCDIC based on the first CCSID_GUESS_BUF_SIZE_ENVAR of the file associated with the given fd. CCSID_GUESS_BUF_SIZE_ENVAR is default at 4KB.

Parameters

[in]

fd

- open file descriptor to guess.

Returns

guessed CCSID (819 for UTF8, 1047 for EBCDIC; otherwise 65535 for BINARY and, if not NULL, errmsg will contain details).

__guess_ue()

int __guess_ue	(	const void *	src,
		size_t	size,
		char *	errmsg,
		size_t	er_size
	)

Guess if string is UTF8 (ASCII) or EBCDIC.

Parameters

[in]	src	- character string.
[in]	size	- number of bytes to analyze.

Returns

guessed CCSID (819 for UTF8, 1047 for EBCDIC; otherwise 65535 for BINARY and, if not NULL, errmsg will contain details).

__set_autocvt_on_fd_stream()

void __set_autocvt_on_fd_stream	(	int	fd,
		unsigned short	ccsid,
		unsigned char	txtflag,
		int	on_untagged_only
	)

Sets file descriptor to auto convert.

Parameters

[in]	fd	- file descriptor.
[in]	ccsid	- CCSID to auto convert to.
[in]	txtflag	- Indicates if ccsid is text.
[in]	on_untagged_only	- applies only to untagged

__set_ccsid_guess_buf_size()

void __set_ccsid_guess_buf_size

(

int

nbytes

)

_convert_a2e()

void * _convert_a2e	(	void *	dst,
		const void *	src,
		size_t	size
	)

Convert from ASCII to EBCDIC

Parameters

[out]	dst	Destination string (must be pre-allocated).
[in]	src	Source string.
[in]	size	Number of bytes to convert

Returns

returns destination string.

_convert_e2a()

void * _convert_e2a	(	void *	dst,
		const void *	src,
		size_t	size
	)

Convert from EBCDIC to ASCII.

Parameters

[out]	dst	Destination string (must be pre-allocated).
[in]	src	Source string.
[in]	size	Number of bytes to convert.

Returns

returns destination string.

conv_utf16_utf8()

int conv_utf16_utf8	(	char *	out,
		size_t	outsize,
		const char *	in,
		size_t	insize
	)

Convert string from UTF16 to UTF8.

conv_utf8_utf16()

int conv_utf8_utf16	(	char *	out,
		size_t	outsize,
		const char *	in,
		size_t	insize
	)

Convert string from UTF8 to UTF16
