fcfgopen()

Open a configuration file

Synopsis:

#include <cfgopen.h>

FILE * fcfgopen( const char * path,
                 const char * mode, 
                 int location,
                 const char * historical, 
                 char * namebuf, 
                 int nblen );

Arguments:

path

The name of the configuration file that you want to open.

mode

A string that describes the mode to open in; see fopen().

location

Flags that describe how the path is constructed. See "Search condition flags" in the documentation for cfgopen().

historical

A optional file to open as a last resort if none of the criteria for finding the path is met. This string works like a path search order, and lets you search more than one location. You can also specify %H to substitute the hostname value into the string. Specify NULL to ignore this option.

namebuf

A buffer to save the pathname in. Specify NULL to ignore this option.

nblen

The length of the buffer pointed to by namebuf. Specify 0 to ignore this option.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

---

This function is in libc.a, but not in libc.so (in order to save space).

Description:

The fcfgopen() function is similar to cfgopen() with these exceptions:

• The CFGFILE_NOFD flag isn't valid.
• The values for flags described in open() aren't valid.

Returns:

A valid fd if CFGFILE_NOFD isn't specified, a nonnegative value if CFGFILE_NOFD is specified, or -1 if an error occurs.

Classification:

QNX Neutrino
