本程序使用C語言讀取類似以下格式的properties文件。 path = /etc/wgetrc launch_on_start = true 下一版目標： （1）使用指針代替二維數據或者二維數據的容量減少至最低要求。 （2）忽略所有空格，忽略空行及注釋行 （3）頭文件規范寫法。 文件1：main.c [cpp] #include <stdio.h> #include "read_properties.h" int main(void){ char names[100][100], values[100][100]; read_properties("/home/lujinhong/scripts/projects/read_properties_file/test.properties", names, values); return 0; } 文件2：read_properties.h [cpp] void read_properties(char *pathname, char names[100][100], char values[100][100]); 文件3：read_properties.c [cpp] /******************************************************************** * This file is used to read the names and values from a properties file, * and store them in an array. * * ******************************************************************/ #include "read_properties.h" #include <stdio.h> #include <unistd.h> #include "utils.h" void read_properties(char *pathname, char names[100][100], char values[100][100]){ FILE *file; char line[100]; int i = 0; file = fopen(pathname, "r"); while(fgets(line, 100, file)){ printf("%s", line); //just for test, delete it later. parseline(line, names[i], values[i]); i++; } fclose(file); } 文件4：utils.h [cpp] void parseline(char *line, char *name, char *value); 文件5：utils.c [cpp] www.2cto.com /*********************************************************** * Parse content of the line, and store the name and value. * line example: path=/etc/wgetrc * * *********************************************************/ void parseline(char *line, char *name, char *value){ int length = 0, equal = 1; //equal will record the location of the '=' char *begin; length = strlen(line); for(begin = line; *begin != '=' && equal <= length; begin ++){ equal++; } strncpy(name, line, equal - 1); line+=equal; strncpy(value, line, length - equal); printf("name = %s value = %s\n", name, value); //just for test, delete it later. } 運行結果： [plain] path = /etc/wgetrc name = path value = /etc/wgetrc launch_on_boot = true name = launch_on_boot value = true
