1.fgets描述 linux下man fgets查手册知道,fgets()会一直读到文件EOF或者一个新行。换行符("\n")会放入fgets指定缓冲区,且末尾后会加入"\0"; fgets() readsinat most one less than size charactersfromstream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline...
On Input, the buffer is filled when an input operation is requested and the buffer is empty. _IOLBF - 行缓冲(Line buffering), 在输入和输出时遇到换行符时才进行真正的I/O操作, 例如标准输入(stdin)和标准输出(stdout). On output, data is written when a newline character is inserted into the...

It includes libprotobuf-c, a pure C library that implements protobuf encoding and decoding, and protoc-gen-c, a code generator plugin for protoc that converts Protocol Buffer .proto files to C descriptor code. protobuf-c formerly included an RPC implementation; that code has been split out...
