-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.
