FILEREAD
FILEREAD attempts to read z storage units (bytes) from file x into location y. It returns the number of storage units actually read.
- x
- File reference
- y
- Expression with type POINTER or OFFSET. If the type is OFFSET, the expression must be an OFFSET variable declared with the AREA attribute.
- z
- Expression. It must have a computational type and is converted to type size_t.1
FILEREAD can read only zFS TYPE(U) files.
