Aug 1, 2003 Since a successful call to lseek returns the new file offset, we can seek to C. ( Similar functionality was provided in Version 6 by the functions

The lseek () family of functions reposition the offset of the open file associated with the file descriptor fd to offset bytes relative to the start, current position, or end of the file, when whence has the value SEEK_SET, SEEK_CUR, or SEEK_END, respectively. For more details, return value, and errors, see lseek (2). The character l in the name lseek means "long integer." Before the introduction of the off_t data type, the offset argument and the return value were long integers. lseek was introduced with Version 7 when long integers were added to C. (Similar functionality was provided in Version 6 by the functions seek and tell. The Standard C Library function is fseek (), though, defined in .

The Microsoft-implemented POSIX function name lseekis a deprecated alias for the _lseekfunction. By default, it generates Compiler warning (level 3) C4996. The name is deprecated because it doesn't follow the Standard C rules for implementation-specific names. However, the function is still supported.

The Standard C Library function is fseek (), though, defined in . Don't mix the two. long lseek (int handle, long offset, int origin); handle == handle of file created by open (), etc.

After the function succeeded and CLMT is created, no FAT access is occured in subsequent f_read/f_write/f_lseek functions to the file. 每一个已打开的文件都有一个读写位置, 当打开文件时通常其读写位置是指向文件开头, 若是以附加的方式打开文件(如O_APPEND), 则读写位置会指向文件尾. 当read()或write()时, 读写位置会随之增加,lseek()便是用来控制该文件的读写位置. That means I have to use lseek rather than fseek, which is fine by me. But what if I want to know how long the file is or what if I want to know where I am pointing. If I had a FILE*, I could use ftell. 2018-10-08 · fseek() in C language, is use to move file pointer to a specific position.
