For help, PHP, FLEX parses PDF, OFFICE, and TEXT documents, similar to Baidu Library principles or source code. just like Baidu Library, after uploading files, you can use FLEX or FLASH to parse the office, pdf, text, ppt, and other files have been investigated in advance. there is an imageMagicX that can parse the pdf into images. I am not very familiar with it.
Method for reading data block functions is as follows:Fread (buffer, size, count, fp), where buffer is a pointer,In the fread function, it indicates the first address for storing input data.Size indicates the number of bytes of the data block.Count indicates the number of data blocks to read and write.Fp indicates the file pointer.For example: fread (fa, fp); the meaning is from the file indicated by fp, each read 4Fread -- read files (which can be safely used for
Abstracttexteditor is the base class of the text editor in eclipse. It class it and implements the corresponding abstract method to get the text editor with the general text editor function, but it is far more than that.
First, let's take a look at what interfaces It implements. The following is the source code of the
can be used to read and write a set of data, such as an array element, a structure variable value, and so on.
The general form of a read block function call is:
Fread (BUFFER,SIZE,COUNT,FP), where buffer is a pointer,
In the Fread function, it represents the first address that holds the input data.
A size represents the number of bytes of data block.
Count represents the number of block blocks of data to read and write.
The FP represents a file pointer.
For example: Fread (FA,4,5,FP); The meani

This is written by a senior. It is very detailed.

Char * P3 = "123456"; 123456 is in the constant zone, and P3 is on the stack.
by row) fgets () each time a row is read, it will point to the next row.
So the first 10 rows are read and cleared.
Then, the next fgets () is 11th rows.
How does fgets () read a row every time? How do you set it?
Fread is a read/write function used to read and write a group of data, such as an array element and a value of a structure variable.
