Detailed Description

Return the entire contents of the input unconnected file or the (remaining) contents of an already-connected file associated with the input unit.

Parameters

[in]	unit	: The input scalar integer of default kind IK containing the unit of an already-connected (opened) file whose (partial) contents will be returned. (optional. It must be present if and only if the input argument file is missing.)
[in]	file	: The input scalar character of default kind SK containing the path of an unconnected (unopened) file whose entire contents will be returned. (optional. It must be present if and only if the input argument unit is missing.)
[out]	contents	: The output allocatable scalar character of default kind SK that will contain the file contents. The allocation status of contents or its value remain undefined if an error occurs. If iostat is present, always check the value of iostat before using contents.
[in]	del	: The input scalar logical of default kind LK. If .true., the file will be deleted upon return. This is guaranteed only if no runtime error occurs. If .false., the file will only be closed (without deletion) upon return. (optional, default = .false.)
[out]	iostat	: The output scalar integer of default kind IK. If present and no error occurs, it is set to 0 on output. If present and an error occurs (e.g., if the input argument values are wrong or inconsistent), it is set to a positive non-zero value. If missing and an error occurs, then the program halts by calling error stop followed by the relevant error message. (optional. It must be present if and only if the output argument iomsg is also present.)
[in,out]	iomsg	: The input/output scalar character of default kind SK of arbitrary length type parameter, containing the error message. A length type parameter value of LEN_IOMSG is generally sufficient for iomsg to contain the output error messages in full. (optional. It must be present if and only if the output argument iostat is also present.)

Possible calling interfaces ⛓

use pm_io, only: setContentsFrom
character(:, SK), allocatable :: contents
 
call setContentsFrom(unit, contents, del = del)
call setContentsFrom(file, contents, del = del)
call setContentsFrom(unit, contents, iostat, iomsg, del = del)
call setContentsFrom(file, contents, iostat, iomsg, del = del)

Warning

The condition isOpen(unit) must hold for the corresponding input arguments.
The condition .not. isOpen(file) must hold for the corresponding input arguments.
The condition 0 < index(getAction(unit), "READ") must hold for the corresponding input arguments.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.

Remarks

The procedures under discussion are impure.
