37 | * | |
38 | * The <a href="http://sigrok.org">sigrok</a> project aims at creating a | |
39 | * portable, cross-platform, Free/Libre/Open-Source signal analysis software | |
40 | * suite that supports various device types (such as logic analyzers, | |
41 | * oscilloscopes, multimeters, and more). | |
42 | * | |
43 | * <a href="http://sigrok.org/wiki/Libsigrok">libsigrok</a> is a shared | |
44 | * library written in C which provides the basic API for talking to | |
45 | * <a href="http://sigrok.org/wiki/Supported_hardware">supported hardware</a> | |
46 | * and reading/writing the acquired data into various | |
47 | * <a href="http://sigrok.org/wiki/Input_output_formats">input/output | |
48 | * file formats</a>. | |
49 | * | |
50 | * @section sec_api API reference | |

52 | * See the "Modules" page for an introduction to various libsigrok | |
53 | * related topics and the detailed API documentation of the respective | |
54 | * functions. | |

82 | * | |
83 | * Initializing and shutting down libsigrok. | |
84 | * | |
85 | * Before using any of the libsigrok functionality (except for | |
86 | * sr_log_loglevel_set()), sr_init() must be called to initialize the | |
87 | * library, which will return a struct sr_context when the initialization | |
88 | * was successful. | |
89 | * | |
90 | * When libsigrok functionality is no longer needed, sr_exit() should be | |
91 | * called, which will (among other things) free the struct sr_context. | |
92 | * | |
93 | * Example for a minimal program using libsigrok: | |
94 | * | |
95 | * @code{.c} | |
96 | * #include <stdio.h> | |
97 | * #include <libsigrok/libsigrok.h> | |
98 | * | |
99 | * int main(int argc, char **argv) | |
100 | * { | |
101 | * int ret; | |
102 | * struct sr_context *sr_ctx; | |
103 | * | |
104 | * if ((ret = sr_init(&sr_ctx)) != SR_OK) { | |
105 | * printf("Error initializing libsigrok (%s): %s.\n", | |
106 | * sr_strerror_name(ret), sr_strerror(ret)); | |
107 | * return 1; | |
108 | * } | |
109 | * | |
110 | * // Use libsigrok functions here... | |
111 | * | |
112 | * if ((ret = sr_exit(sr_ctx)) != SR_OK) { | |
113 | * printf("Error shutting down libsigrok (%s): %s.\n", | |
114 | * sr_strerror_name(ret), sr_strerror(ret)); | |
115 | * return 1; | |
116 | * } | |
117 | * | |
118 | * return 0; | |
119 | * } | |
