int MM_OpenConfigFile()

Availability

Dreamweaver MX.

Description

This function opens the file and returns an operating system file handle. You can use the

operating system file handle in calls to system file functions. You must close the file handle

with a call to the system

_close function.

If the file is a configuration file, it finds the file in either the user Configuration folder or the

Dreamweaver Configuration folder. If you open the Configuration file for writing, the

function creates the file in the user Configuration folder, even if it exists in the Dreamweaver

Configuration folder.

Arguments

char *fileURL, char *mode

■ The char *fileURL argument is a pointer to a string that names the file that you are

opening, which is provided as a file:// URL. If it specifies a path in the Dreamweaver

Configuration folder, the

MM_OpenConfigFile() function resolves the path before

opening the file.

■ The char *mode argument points to a string that specifies how you want to open the file.

You can specify

null, "read", "write", or "append" mode. If you specify "write" and

the file does not exist, the

MM_OpenconfigFile() function creates it. If you specify

write", the MM_OpenConfigFile() function opens the file with an exclusive share. If

you specify "

read", the MM_OpenConfigFile() function opens the file with a

nonexclusive share.

If you open the file in "

write" mode, any existing data in the file is truncated before

writing new data. If you open the file in "

append" mode, any data you write is appended

to the end of the file.

Returns

An integer that is the operating system file handle for this file. Returns -1 if the file cannot be

found or does not exist.

NOTE

If you want to read the file before writing to it, open the file in "read" mode. When you

want to write to the file, close the read handle and open the file again in "

write" or

append" mode.
