Function Documentation

int ccp4_licence_exists (  const char *    name )

Check existence of licence agreement Parameters: name  Name of licence, e.g. "CCP4". Returns: 1 for licence exists, else 0.

char* ccp4_prog_vers (  char *    progvers )

Register or query program version. Parameters: progvers  Program version string, or NULL to query existing value. Returns: Program version string.

int ccp4Callback (  CCP4INTFUNCPTR    mycallback, char *    mode, int    ierr, char *    message )

Set or invoke a user-defined callback function The callback must be of the form "function(const int, const char *)" This is essentially an internal function which operates in one of two modes - in "set" mode the named function is stored and the remaining arguments are discarded; in "invoke" mode the stored function is executed with the supplied values (the supplied name is discarded). Parameters: mycallback  Callback function (discarded in "invoke" mode) mode  Either "set" or "invoke" ierr  An error level equivalent to that used in ccperror message  A message string equivalent to that used in ccperror Returns: Result of the executed function (invoke mode)

int ccp4InvokeCallback (  int    ierr, char *    message )

Invoke the user-defined callback function This is a wrapper to ccp4Callback - it executes the user-defined callback function previously stored. Parameters: ierr  An error level equivalent to that used in ccperror message  A message string equivalent to that used in ccperror Returns: Result of the executed function

int ccp4NullCallback (  int    level, char *    message )

A dummy callback function used by default in ccp4CallOnExit Internal function. This function does nothing. Parameters: level  Severity level supplied from ccperror message  Message text supplied from ccperror Returns: Always returns 1

char* ccp4ProgramName (  const char *    progname )

Set or return program name. Parameters: progname  Program name, or NULL to query existing value. Returns: Program name

void ccp4ProgramTime (  int    init )

Set or print program time information Parameters: init

char* ccp4RCSDate (  const char *    rcs_string )

Set or return program RCS date Parameters: rcs_string  Date string, or NULL to query existing value. Returns: Date string

int ccp4SetCallback (  CCP4INTFUNCPTR    mycallback )

Set a user-defined callback function This is a wrapper to ccp4Callback - it stores a user-defined callback function which must be of the form "function(const int, const char *)" Parameters: mycallback  Callback function Returns: 1 (if the function is stored), 0 (if it is not)

int ccp4VerbosityLevel (  int    level )

Set or return the reference verbosity level Always return the verbosity level - if verboselevel is between 0 and 9 then reset the verbosity level to verboselevel Parameters: level  Verbosity level, or -1 to query existing value. Returns: Verbosity level

int html_log_output (  int    ihtml_in )

Register or query html output level. Parameters: ihtml_in  0 = turn off html output, 1 = turn on html output, -1 = query existing value Returns: 0 = no html output, 1 = html output

int summary_output (  int    isumm_in )

Register or query summary output level. Parameters: isumm_in  0 = turn off summary output, 1 = turn on summary output, -1 = query existing value Returns: 0 = no summary output, 1 = summary output
