Function Documentation

◆ __attribute__()

const unsigned char __ibm1047_iso88591[256] __attribute__ ( (aligned(8))  )

◆ __convert_one_to_one()

void *__Z_EXPORT __convert_one_to_one ( const void *  table,
void *  dst,
size_t  size,
const void *  src 
)
inline

◆ __fd_close()

__Z_EXPORT void __fd_close ( int  fd)

Unsets fd attributes

Parameters
[in]fdfile descriptor

◆ __file_needs_conversion()

__Z_EXPORT 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]fdfile descriptor
Returns
returns 1 if file needs conversion, 0 if not.

◆ __file_needs_conversion_init()

__Z_EXPORT int __file_needs_conversion_init ( const char *  name,
int  fd 
)

Determines if file needs conversion from EBCDIC to ASCII.

Parameters
[in]namepath to file
[in]fdfile descriptor
Returns
returns 1 if file needs conversion, 0 if not.

◆ __guess_ae()

__Z_EXPORT 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()

__Z_EXPORT 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()

__Z_EXPORT 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()

__Z_EXPORT 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

◆ _convert_a2e()

__Z_EXPORT void * _convert_a2e ( void *  dst,
