ReadSignedLongIntegerArray

SIGNED_INTEGER ReadSignedLongIntegerArray ( INTEGER 

file_handle, 

SIGNED_LONG_INTEGER sliArray[m][n] ) 

Reads the array from a file starting at the current file position. Two bytes are read, 
most significant first containing the row dimension of the array, then two more bytes 
are read, containing the column dimension of the array. Then each signed long integer 
is read as a four byte quantity, most significant byte first. The integers are stored in 
row-major order, e.g. all the elements of row 0 first, then the elements of row 1, etc. 
Note that there is one more row and one more column than the dimensions that are 
read, because there is a row 0 and a column 0. Refer to the section entitled “Reading 
and Writing Data to a File” on page 

 for a discussion of when to use this function 

and when to use the related functions: FileRead, ReadInteger, ReadString, 
ReadStructure, ReadSignedInteger, ReadLongInteger, ReadLongSignedInteger, 
ReadIntegerArray, ReadSignedIntegerArray, ReadLongIntegerArray, 
ReadLongSignedIntegerArray, ReadStringArray.

FILE_HANDLE specifies the file handle of the previously opened file (from 
FileOpen). 

SLIARRAY is the array whose values are read.  

Number of bytes read from file. If the return value is negative, it is an error code. 

NOTE: Input and Output variables of any kind are not allowed in the file read 
functions.
