# Utility function to call a function if it exists.
|
|
#
|
|
# Usage: _funcall <return> <name> [ <args> ... ]
|
|
#
|
|
# If a function named <name> is defined (or defined to be autoloaded),
|
|
# it is called. If <return> is given not the string `-' or empty, it is
|
|
# taken as the name of a parameter and the return status of the function
|
|
# called is stored in this parameter. All other arguments are given
|
|
# to the function called.
|
|
# The return value of this function is zero if the function was
|
|
# called and non-zero otherwise.
