Returns the index of substring that occurs in values for a memory buffer.

function MemoryPos(const ASubStr: String; MemBuff: PChar; MemorySize: Integer): Integer;

Value to be located in the memory buffer.

Memory buffer to be searched.

Size of the memory buffer to be searched.

Integer - Position of the substring the memory buffer.

MemoryPos is an Integer function used to determine the index value of the first character in a specified substring that occurs in a memory buffer.

ASubStr is the string value to be located in the memory buffer specified by the PChar MemBuff. MemoryPos searches for ASubStr within MemBuff, and returns an integer value that is the index of the first character of ASubStr within MemBuff.

MemoryPos is case-sensitive. If ASubStr is not found, MemoryPos returns zero.
