C语言的库函数的源代码我们能不能看到？

       这个看情况了。实际上库函数的数库数库joffice2.0源码大部分功能没有写到代码里面。

       以windows为例，语言函源码c语言函源码斗地主完整源码它是数库数库流量统计系统源码在build程序时的连接阶段和相关的代码结合的。

       实际上它真正的语言函源码c语言函源码作妖记源码工作方式也不在那些obj文件中，而obj文件是数库数库房产cms源码下载编译好了，读不了的语言函源码c语言函源码文件。

c语言标准函数库<stdio.h>

       Functions for file input/output:

       int fgetc(FILE* stream);- Returns the next character from (input) stream stream,数库数库 or EOF on end-of-file or error.

       char* fgets(char* s, int n, FILE* stream);- Copies characters from (input) stream stream to s, stopping when n-1 characters copied, newline copied, end-of-file reached or error occurs. Returns NULL on end-of-file or error, s otherwise.

       int fputc(int c, FILE* stream);- Writes c to stream stream. Returns c, or EOF on error.

       char* fputs(const char* s, FILE* stream);- Writes s to (output) stream stream. Returns non-negative on success or EOF on error.

       int getc(FILE* stream);- Equivalent to fgetc except that it may be a macro.

       int getchar(void);- Equivalent to getc(stdin).

       char* gets(char* s);- Copies characters from stdin into s until newline encountered, end-of-file reached, or error occurs. Does not copy newline. NUL-terminates s. Returns s, or NULL on end-of-file or error. Should not be used because of the potential for buffer overflow.

       int putc(int c, FILE* stream);- Equivalent to fputc except that it may be a macro.

       int putchar(int c);- Equivalent to putc(c, stdout).

       int puts(const char* s);- Writes s (excluding terminating NUL) and a newline to stdout. Returns non-negative on success, EOF on error.

       int ungetc(int c, FILE* stream);- Pushes c (which must not be EOF), onto (input) stream stream such that it will be returned by the next read. Only one character of pushback is guaranteed (for each stream).

       size_t fread(void* ptr, size_t size, size_t nobj, FILE* stream);- Reads (at most) nobj objects of size size from stream stream into ptr and returns number of objects read.

       size_t fwrite(const void* ptr, size_t size, size_t nobj, FILE* stream);- Writes to stream stream, nobj objects of size size from array ptr. Returns number of objects written.

       int fseek(FILE* stream, long offset, int origin);

       ftell(FILE* stream):

       Sets the streamstream's file position and clears the end-of-file flag. For binary streams, the position is set to offset bytes from origin. For text streams, behavior is similar but offset must be zero or only when ftell returns the value for SEEK_SET. Returns non-zero on error.

       long ftell(FILE* stream):

       Returns the current file position of streamstream, returns -1 on error.

       rewind(FILE* stream):

       Equivalent to fseek(stream, 0L, SEEK_SET)and clears error and end-of-file flags of stream.

       fgetpos(FILE* stream, fpos_t* ptr):

       Stores the current file position of streamstream in *ptr. Returns non-zero on error.

       fsetpos(FILE* stream, const fpos_t* ptr):

       Sets the position of streamstream to *ptr. Returns non-zero on error.

       clearerr(FILE* stream):

       Clears the error and end-of-file flags of streamstream.

       feof(FILE* stream):

       Returns non-zero value if the end-of-file flag of streamstream is set.

       ferror(FILE* stream):

       Returns non-zero value if the error flag of streamstream is set.

       perror(const char* s):

       Prints (if not empty) and strerror(errno) to standard error, similar to using fprintf(stderr, "%s: %s\n", (s != NULL ? s : ""), strerror(errno)).
