F_SplitPathName

FUNCTION F_SplitPathName : BOOL

VAR_INPUT
    sPathName : T_MaxString;
END_VAR

sPathName: Complete file name as string: 'X:\DIR\SUBDIR\FILENAME.EXT'.

VAR_IN_OUT
    sDrive    : STRING(3);
    sDir      : T_MaxString;
    sFileName : T_MaxString;
    sExt      : T_MaxString;
END_VAR

sDrive: Drive name with a double point ('C:', 'A:' etc.).

sDir: Directory name inlusive the leading and ending backslash ('\BC \INCLUDE\', '\SOURCE\' etc.).

sFileName: File name.

sExt: Contains the point that starts the name extension ('.C', '.EXE' etc.).

Example for a call in ST:

The path name: 'C:\TwinCAT\Plc\Project01\Data.txt' is splitted in the following components:

sDrive: = 'C:'

sDir: '\TwinCAT\Plc\Project01\'

sFileName: 'Data'

sExt: '.txt'
