NAME
atBindAddRule, atBindDelRule, atBindRuleFile, atBindDisplayErrors,
atBindTestRule, atBindShowRules, atBindListRules - version bind rule
handling
SYNOPSIS
#include <atfs.h>
#include <atfstk.h>
int atBindAddRule (char *ruleName, char *ruleBody, char *srcFile, int
srcLine);
int atBindDelRule (char *ruleName);
int atBindRuleFile (char *fileName);
int atBindDisplayErrors;
int atBindTestRule (char *ruleName);
int atBindShowRules (void);
char**atBindListRules (void);
DESCRIPTION
The atBind module maintains an internal database storing all known
version bind rules.
The atBindAddRule function stores a new rule in the internal database.
It expects the rule name, optionally including parameter definitions,
and the rule body as string arguments. Additionally, the filename
(srcFile) of the file, where the rule is read from, and the line within
that file (srcLine), may be given. This is used for producing proper
error messages. atBindAddRule returns -1 on error, 0 otherwise.
atBindDelRule removes a previously defined rule from the internal
database. It returns a negative return value (-1), when no rule with
the given name was not found in the internal database.
The atBindRuleFile function scans a file containing version bind rules
and adds all contained rules to the internal database. It returns the
number of version bind rules successfully added to the internal
database. A zero return value may also indicate an error.
The switch atBindDisplayErrors may be set TRUE to enable error
reporting during parsing of version binding rules. Error messages will
be written directly to standard error. Initially, atBindDisplayErrors
is set FALSE.
AtBindTestRule reports whether ruleName is defined as version binding
rule or not. It returns a non zero (TRUE) value when the name is
defined, otherwise FALSE.
atBindShowRules dumps the internal database to the standard output.
Return value is always TRUE.
atBindListRules returns all known bind rule names in a list. The list
memory is allocated by use of malloc(3). On error, atBindListRules
returns a null pointer.
DIAGNOSTICS
Upon error, each routine returns a null value, the variable atBindError
is set true (non-zero), and an explaining message is copied to the
atBindErrorMsg string buffer. The atBindError variable is cleared upon
successful calls, the message buffer remains unchanged.
ENVIRONMENT
SHAPETOOLS - list of path names as search space for files containing
version bind rules. The bind rule files must be named BindRules.
Default path is /usr/local/lib/shape.
