NAME

getconfent, getconfent_r - Get configuration entry

SYNOPSIS


char * getconfent (


               const char *category,


               const char *name,


               int flags);

char * getconfent_r (


               const char *category,


               const char *name,


               int flags,


               char *buffer,


               int bufsiz);

DESCRIPTION

getconfent() get the name entry from the configuration file. Every entry in the configuration file is categorized. The category parameter is its specifier. The getconfent_r() function is a re-entrant version of getconfent() using the passed buffer parameter instead of an internal static buffer.

If threads are created usint the Cthread_create() interface, it is not mandatory to call getconfent_r() in order to assure thread-safe code. In that case getconfent() calls the re-entrant version internally using a buffer allocated in thread local storage.

RETURN VALUE

getconfent() and getconfent_r() return NULL if the entry is not found. Otherwise, it returns the matched entry. If flags is not null, the return value is a pointer to the full string matched in the configuration file. Otherwise, only the pointer to the first blank separated token is returned.

ERRORS

If the getconfent(), getconfent_r() function fail, serrno may be set to one of the following values:

SENOCONFIG: configuration file not found.
