将字符串写到文件中

int iWriteStr2File(char *pContent,const char * pFileName){
	int iSize = strlen(pContent);
	if(iSize<0){
		return -1;
	}
	int iRet=0;
	FILE * pf;
	pf = fopen(pFileName,"wb");
	if(pf==NULL){
		iRet = -2;
		return iRet;
	}
	do 
	{
		int iWrote = fwrite(pContent,1,iSize,pf);
		if(iWrote!=iSize){
			iRet = -3;
			break;
		}
	} while (0);
	fclose(pf);
	return iRet;
}
