Functions i mysys: (For flags se my_sys.h)
int my_copy _A((const char *from,const char *to,myf MyFlags));
- Copy file
int my_delete _A((const char *name,myf MyFlags));
- Delete file
int my_getwd _A((string buf,uint size,myf MyFlags));
int my_setwd _A((const char *dir,myf MyFlags));
- Get and set working directory
string my_tempnam _A((const char *pfx,myf MyFlags));
- Make a uniq temp file name by using dir and adding something after
pfx to make name uniq. Name is made by adding a uniq 6 length-string
and TMP_EXT after pfx.
Returns pointer to malloced area for filename. Should be freed by
free().
File my_open _A((const char *FileName,int Flags,myf MyFlags));
File my_create _A((const char *FileName,int CreateFlags,
int AccsesFlags, myf MyFlags));
int my_close _A((File Filedes,myf MyFlags));
uint my_read _A((File Filedes,byte *Buffer,uint Count,myf MyFlags));
uint my_write _A((File Filedes,const byte *Buffer,uint Count,
myf MyFlags));
ulong my_seek _A((File fd,ulong pos,int whence,myf MyFlags));
ulong my_tell _A((File fd,myf MyFlags));
- Use instead of open,open-with-create-flag, close read and write
to get automatic error-messages (flag: MYF_WME) and only have
to test for != 0 if error (flag: MY_NABP).
int my_rename _A((const char *from,const char *to,myf MyFlags));
- Rename file
FILE *my_fopen _A((const char *FileName,int Flags,myf MyFlags));
FILE *my_fdopen _A((File Filedes,int Flags,myf MyFlags));
int my_fclose _A((FILE *fd,myf MyFlags));
uint my_fread _A((FILE *stream,byte *Buffer,uint Count,myf MyFlags));
uint my_fwrite _A((FILE *stream,const byte *Buffer,uint Count,
myf MyFlags));
ulong my_fseek _A((FILE *stream,ulong pos,int whence,myf MyFlags));
ulong my_ftell _A((FILE *stream,myf MyFlags));
- Same read-interface for streams as for files
gptr _mymalloc _A((uint uSize,const char *sFile,
uint uLine, myf MyFlag));
gptr _myrealloc _A((string pPtr,uint uSize,const char *sFile,
uint uLine, myf MyFlag));
void _myfree _A((gptr pPtr,const char *sFile,uint uLine));
int _sanity _A((const char *sFile,unsigned int uLine));
gptr _myget_copy_of_memory _A((const byte *from,uint length,
const char *sFile, uint uLine,
myf MyFlag));
- malloc(size,myflag) is mapped to this functions if not compiled
with -DSAFEMALLOC
void TERMINATE _A((void));
- Writes malloc-info on stdout if compiled with -DSAFEMALLOC.
int my_chsize _A((File fd,ulong newlength,myf MyFlags));
- Change size of file
void my_error _D((int nr,myf MyFlags, ...));
- Writes message using error number (se mysys/errors.h) on
stdout or curses if MYSYS_PROGRAM_USES_CURSES() is called.
void my_message _A((const char *str,myf MyFlags));
- Writes message-string on
stdout or curses if MYSYS_PROGRAM_USES_CURSES() is called.
void my_init _A((void ));
- Start each program (in main) with this.
void my_end _A((int infoflag));
- Gives info about program.
- If infoflag & MY_CHECK_ERROR prints if some files are left open
- If infoflag & MY_GIVE_INFO prints timing info and malloc info
about prog.
int my_redel _A((const char *from, const char *to, int MyFlags));
- Delete from before rename of to to from. Copyes state from old
file to new file. If MY_COPY_TIME is set sets old time.
int my_copystat _A((const char *from, const char *to, int MyFlags));
- Copye state from old file to new file.
If MY_COPY_TIME is set sets copy also time.
string my_filename _A((File fd));
- Give filename of open file.
int dirname _A((string to,const char *name));
- Copy name of directory from filename.
int test_if_hard_path _A((const char *dir_name));
- Test if dirname is a hard path (Starts from root)
void convert_dirname _A((string name));
- Convert dirname acording to system.
- In MSDOS changes all caracters to capitals and changes '/' to
'\'
string fn_ext _A((const char *name));
- Returns pointer to extension in filename
string fn_format _A((string to,const char *name,const char *dsk,
const char *form,int flag));
format a filename with replace of library and extension and
converts between different systems.
params to and name may be identicall
function dosn't change name if name != to
Flag may be: 1 force replace filnames library with 'dsk'
2 force replace extension with 'form' */
4 force Unpack filename (replace ~ with home)
8 Pack filename as short as possibly for output to
user.
All open requests should allways use at least:
"open(fn_format(temp_buffe,name,"","",4),...)" to unpack home and
convert filename to system-form.
string fn_same _A((string toname,const char *name,int flag));
- Copys directory and extension from name to toname if neaded.
copy can be forced by same flags that in fn_format.
int wild_compare _A((const char *str,const char *wildstr));
- Compare if str matches wildstr. Wildstr can contain "*" and "?"
as match-characters.
Returns 0 if match.
void get_date _A((string to,int timeflag));
- Get current date in a form ready for printing.
void soundex _A((string out_pntr, string in_pntr))
- Makes in_pntr to a 5 chars long string. All words that sounds
alike have the same string.
int init_key_cache _A((ulong use_mem,ulong leave_this_much_mem));
- Use cacheing of keys in MISAM, PISAM, and ISAM.
KEY_CACHE_SIZE is a good size.
- Remember to lock databases for optimal cacheing
void end_key_cache _A((void));
- End key-cacheing.
