2000-10-09 Havoc Pennington <hp@redhat.com> * Makefile.am, tests/Makefile.am: Add new files. * tests/spawn-test.c, tests/shell-test.c: new tests for the shell/spawn stuff * gutils.c (g_find_program_in_path): convert a relative program name into an absolute pathname to an existing executable * gspawn.h, gspawn.c: New fork/exec API * gshell.h, gshell.c: Shell-related utilities, at the moment simply routines to parse argv and quote/unquote strings * guniprop.c (g_unichar_isspace): Return TRUE for the ASCII space characters isspace() returns TRUE for. * gfileutils.c (g_file_get_contents): Convenience function to slurp entire file into a string and return it. Partially written by Joel Becker. (g_file_test): file test function
