From: Tzvetomir Stoyanov (VMware) Date: Wed, 8 Aug 2018 18:03:07 +0000 (-0400) Subject: tools lib traceevent: Rename internal parser related APIs X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1634e4604cccbe6394dd858fb973604d2313336b;p=openwrt%2Fstaging%2Fblogic.git tools lib traceevent: Rename internal parser related APIs In order to make libtraceevent into a proper library, variables, data structures and functions require a unique prefix to prevent name space conflicts. That prefix will be "tep_" and not "pevent_". This changes APIs: pevent_buffer_init, pevent_read_token, pevent_free_token, pevent_peek_char, pevent_get_input_buf, pevent_get_input_buf_ptr Signed-off-by: Tzvetomir Stoyanov (VMware) Cc: Andrew Morton Cc: Peter Zijlstra Cc: Yordan Karadzhov (VMware) Cc: linux-trace-devel@vger.kernel.org Link: http://lkml.kernel.org/r/20180808180703.275281085@goodmis.org Signed-off-by: Steven Rostedt Signed-off-by: Arnaldo Carvalho de Melo --- diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index d367f7f2f2fc..8215e6ff36eb 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -73,12 +73,12 @@ static void init_input_buf(const char *buf, unsigned long long size) input_buf_ptr = 0; } -const char *pevent_get_input_buf(void) +const char *tep_get_input_buf(void) { return input_buf; } -unsigned long long pevent_get_input_buf_ptr(void) +unsigned long long tep_get_input_buf_ptr(void) { return input_buf_ptr; } @@ -113,14 +113,14 @@ process_defined_func(struct trace_seq *s, void *data, int size, static void free_func_handle(struct tep_function_handler *func); /** - * pevent_buffer_init - init buffer for parsing + * tep_buffer_init - init buffer for parsing * @buf: buffer to parse * @size: the size of the buffer * - * For use with pevent_read_token(), this initializes the internal - * buffer that pevent_read_token() will parse. + * For use with tep_read_token(), this initializes the internal + * buffer that tep_read_token() will parse. */ -void pevent_buffer_init(const char *buf, unsigned long long size) +void tep_buffer_init(const char *buf, unsigned long long size) { init_input_buf(buf, size); } @@ -913,11 +913,11 @@ static int __peek_char(void) } /** - * pevent_peek_char - peek at the next character that will be read + * tep_peek_char - peek at the next character that will be read * * Returns the next character read, or -1 if end of buffer. */ -int pevent_peek_char(void) +int tep_peek_char(void) { return __peek_char(); } @@ -1157,7 +1157,7 @@ static enum event_type read_token(char **tok) } /** - * pevent_read_token - access to utilites to use the pevent parser + * tep_read_token - access to utilites to use the pevent parser * @tok: The token to return * * This will parse tokens from the string given by @@ -1165,16 +1165,16 @@ static enum event_type read_token(char **tok) * * Returns the token type. */ -enum event_type pevent_read_token(char **tok) +enum event_type tep_read_token(char **tok) { return read_token(tok); } /** - * pevent_free_token - free a token returned by pevent_read_token + * tep_free_token - free a token returned by tep_read_token * @token: the token to free */ -void pevent_free_token(char *token) +void tep_free_token(char *token) { free_token(token); } diff --git a/tools/lib/traceevent/event-parse.h b/tools/lib/traceevent/event-parse.h index 7f8921431cf1..c41547353b4c 100644 --- a/tools/lib/traceevent/event-parse.h +++ b/tools/lib/traceevent/event-parse.h @@ -797,12 +797,12 @@ void pevent_ref(struct tep_handle *pevent); void pevent_unref(struct tep_handle *pevent); /* access to the internal parser */ -void pevent_buffer_init(const char *buf, unsigned long long size); -enum event_type pevent_read_token(char **tok); -void pevent_free_token(char *token); -int pevent_peek_char(void); -const char *pevent_get_input_buf(void); -unsigned long long pevent_get_input_buf_ptr(void); +void tep_buffer_init(const char *buf, unsigned long long size); +enum event_type tep_read_token(char **tok); +void tep_free_token(char *token); +int tep_peek_char(void); +const char *tep_get_input_buf(void); +unsigned long long tep_get_input_buf_ptr(void); /* for debugging */ void tep_print_funcs(struct tep_handle *pevent); diff --git a/tools/lib/traceevent/parse-filter.c b/tools/lib/traceevent/parse-filter.c index 3efab9b4298f..5e3f29736a25 100644 --- a/tools/lib/traceevent/parse-filter.c +++ b/tools/lib/traceevent/parse-filter.c @@ -51,8 +51,8 @@ static void show_error(char *error_buf, const char *fmt, ...) int len; int i; - input = pevent_get_input_buf(); - index = pevent_get_input_buf_ptr(); + input = tep_get_input_buf(); + index = tep_get_input_buf_ptr(); len = input ?
