/********************************************************************* ** ** This program is offer two function GetIniValue() and SetIniValue() ** to access ini file, to get a value from ini file just call GetIni- ** Value(IniFilename, GroupName, ValueName, Value). to set a value in ** ini file, just call SetIniValue(IniFileName, GroupName, ValueName, ** Value), when ini file not found, SetIniValue() function will create ** it. if group name or value name not found, SetIniFile() will create ** it and then set the value. ** ** Note: 1. in ini file, '#' is a comment charater, the content follow- ** ed it will be ignored; ** 2. group name, value name and value is a string that must not ** include space or tab character; ** 3. the length of group name, value name and value must less ** than 100; ** 4. in ini file group name is like [abc]. it must within '[' and ** ']'; ** 5. when get value from ini file, all space and tab are ignored; ** 6. max length of a line is less than 1000. ** Return value: ** GetIniValue: ** 0: suceess ** -11: can not open ini file ** -22: pointer to the value is null ** -21: value not found ** ** SetIniValue: ** 0: suceess ** -11: can not open ini file ** -12: write value error ** -20: alloc memory error ** -100: unknow error due to fseek ** Ini file example: ** [groupname] ** valuename = value #this a example ** *********************************************************************** */ #include <stdlib.h> #include <stdio.h> #include <unistd.h> #include <sys/types.h> #include "readini.h" #include "myerror.h" /*去除字符串中的空白字符*/ void TrimSpace(char *sSource); void SetValue(char *sValue, char *sBuff); int WriteRemain(FILE *fpIniFile, long lReadPosition, long lWritePosition, char *sWriteBuff ); /* ** this function is to get value from ini file. ** ** ** Note: 1.
