annotate src/oct-parse.yy @ 12918:f3a8d1efe2c1 stable
use gnulib:: qualifiers for more stdio functions
* oct-parse.yy (text_getc): Use gnulib::getc instead of getc.
(looking_at_classdef_keyword, looking_at_funciton_keyword):
Use gnulib::ftell, gnulib::fseek, and gnulib::fgets instead of
ftell, fseek, and fgets.
* file-io.cc (Fmkstemp): Use gnulib::mkstemp instead of mkstemp.
* lo-utils.cc (octave_fgets): Use gnulib::fgets instead of fgets.
* c-file-ptr-stream.h (c_file_ptr_buf::seek):
Use gnulib::fseek instead of fseek.
(c_file_ptr_buf::tell): Use gnulib::ftell instead of ftell.
