pm_io::setContentsTo Interface Reference

Write the input string contents to the input unconnected file.
More...

Detailed Description

Write the input string contents to the input unconnected file.

This generic interface in its current form is a simple wrapper around the open() and write() intrinsic statements to simplify writing to output files.

Parameters

[in]	file	: The input scalar character of default kind SK containing the path of an unconnected (unopened) file.
[in]	contents	: The input scalar character of default kind SK that containing the contents to write to the target external file.
[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: setContentsTo
character(:, SK), allocatable :: contents
 
call setContentsTo(file, contents = del)
call setContentsTo(file, contents, iostat, iomsg = del)

Warning

The condition .not. isOpen(file) 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.

Todo:

Normal Priority: This generic interface must be expanded to input unit in place of an input file.
There are potential complexities associated with an input unit that need inquire statement such as access, form, etc.
