FEXECL(3) Schily's LIBRARY FUNCTIONS FEXECL(3)
NAME fexecl() - executes a program
SYNOPSIS fexecl(name, in, out, err, arg0, arg1, ... argn, NULL) char *name; FILE *in, *out, *err; char *arg0...*argn;
DESCRIPTION fexecl() is a variation of fexecve(). The description of fexecve() applies to fexecl(), with two exceptions. First, fexecl() does not permit the environment list to be specified; it causes the new program to have the same environment as the current program, using the global environment pointer environ. Second, the argument list for the new program is constructed as part of the call to fexecl(). This is a lot easier to write than the code to construct a vector of strings, but is limited to cases with a fixed number of arguments. The argument list will consist of the strings a0, a1, and so on. By convention, a0 is the name of the new program.
RETURNS Returns system error code; doesn't return if successful.
