◆ gcov_close()
| GCOV_LINKAGE int gcov_close | ( | void | ) |
Close the current gcov file. Flushes data to disk. Returns nonzero on failure or error flag set.

◆ gcov_is_error()

inlinestatic |
Return nonzero if the error flag is set.
We need to expose this function when compiling for gcov-tool.

◆ gcov_magic()
| GCOV_LINKAGE int gcov_magic | ( | gcov_unsigned_t | magic, |
| gcov_unsigned_t | expected ) |
Check if MAGIC is EXPECTED. Use it to determine endianness of the file. Returns +1 for same endian, -1 for other endian and zero for not EXPECTED.
References gcov_var::endian.
Referenced by dump_gcov_file(), read_count_file(), read_counts_file(), and read_graph_file().
◆ gcov_open()
| GCOV_LINKAGE int gcov_open | ( | const char * | name, |
| int | mode ) |
Open a gcov file. NAME is the name of the file to open and MODE indicates whether a new file should be created, or an existing file opened. If MODE is >= 0 an existing file will be opened, if possible, and if MODE is <= 0, a new file will be created. Use MODE=0 to attempt to reopen an existing file and then fall back on creating a new one. If MODE > 0, the file will be opened in read-only mode. Otherwise it will be opened for modification. Return zero on failure, non-zero on success.
