File_OpenPath()
Syntax
File_OpenPath(ByRef PathString As Dword, pMode As Bit), Byte
Parameters
PathString — source string buffer array — a string variable is required here, since ByRef passes its address automatically
pMode — 0 - Open file
1 - Append file
Return value
pMode — 0
cErrOK: Success.
cErrNotFound: File not found.
cErrInUse: File number is already in use.
cErrDiskFull: Disk is full or directory wasn't found
cErrRWError: Read/write error.
pMode — 1
cErrOK: Success.
cErrNotFound: File not found.
cErrDiskFull: Disk is full or directory wasn't found
cErrInUse: File is already open and in use.
cErrRWError: Read/write error.
Opens a file given a full path
Opens a file given a full path (e.g. "LOGS/2026/07/DATA.CSV" or "/LOGS/2026/07/DATA.CSV").
Splits off the last "/"-separated segment as the filename and walks the rest via FAT_WalkPath() (same directory-parsing as File_MkPath()/File_SetPath(), but without creating missing directories - a missing directory here is an error, not something to create).
A path with no "/" at all is treated as a bare filename in the current directory (same as File_Open() directly).
Example

Dim sTemp As String * 24 'Create string array variable sTemp = "home/is/here/temp.txt" 'Place some path to a file in this string variable File_OpenPath(sTemp,1) 'Open temp.txt ready to append data |
