Typedef Documentation

◆ pm_parse_stream_fgets_t

typedef char *() pm_parse_stream_fgets_t(char *string, int size, void *stream)

This function is used in pm_parse_stream() to retrieve a line of input from a stream.

It closely mirrors that of fgets so that fgets can be used as the default implementation.

◆ pm_parse_stream_feof_t

typedef int() pm_parse_stream_feof_t(void *stream)

This function is used in pm_parse_stream to check whether a stream is EOF.

It closely mirrors that of feof so that feof can be used as the default implementation.
