Callgrind 用于分析程序的函数调用情况，可以生成函数调用图和统计信息。使用方式：valgrind --tool=callgrind [program name]以上是一些常用的 Valgrind 工具及其使用方式，根据具体的需求选择相应的工具进行检测和优化。常见错误 当使用 Valgrind 进行内存检查时，会遇到多种不同的错误和警告信息。下面是一些常见的错误...
11、 Extra parameter in call ‘fun’ 调用函数fun时给出了多余的实参。 12、 Function should return a value 函数应该返回一个值,否则与定义时的说明类型不匹配。 13、 Illegal use of pointer 指针被非法引用,一般是使用了非法的指针运算。 14、 Invalid pointer addition 指针相加非法。一个指针(地址)可以和...
#cc program.c 生成a.out文件 这个名字是编译器默认的输出名。如果要修改可执行文件的名字可以加-o参数:gcc -o myexec main.c 这样就把main.c编译连接生成的可执行文件命名为myexec gcc编译器的编译自定义格式 #cc -o hello hello.c #gcc -o hello hello.c ...

longjmp() restores the environment saved by the last call of setjmp(3) with the corresponding env argument. After longjmp() is completed, program execution continues as if the corresponding call of setjmp(3) had just returned the value val. longjmp() cannot cause 0 to be returned. If longjm...
